Red rectangular post box attached to black metal railings in front of a large white house. It has no Royal cypher on it. There is a sticker on it that says 'ROYAL MAIL'. Underneath is an official Royal Mail collection plate.

Is it a lamp box or a wall box? No, it's a railings box! Would I ever post anything in it? Absolutely not, but it is a bona fide Royal Mail post box that is cleared once a day apart from Sundays. 📮 #postboxsaturday #PostBoxDiary

Red VR pillar box with a brass plaque on the front of it commemorating the Manchester bombing in 1996. The pillar box remained standing despite the rest of the area around it being badly damaged. The surrounding buildings are now all new shopping units.

Still standing, still serving a purpose, when everything else around you has changed beyond recognition. 📮 #postboxsaturday #PostBoxDiary

Red Type C double aperture pillar box. Across the road is an old blue police box better known as Doctor Who's TARDIS. It is in front of Earls Court Underground Station.

I think Doctor Who was just stopping by to post a letter about the 1960s episodes that have been found. They will be shown for the first time since 1965 later this year. 📮 #postboxsaturday #PostBoxDiary

Victorian red pillar box positioned by the side of the pavement. In front of it is a sign saying, 'NO IDLING ZONE' with a picture of a car with exhaust emissions coming out of it in a red circle with a red line through it.

Red pillar box that has been converted to a solar parcel box. The converted door has been repainted but the back and black base of the pillar has been left. To the side of the post box is a sign for the Majestic Wine Warehouse.

Not looking that majestic...This poor pillar box didn't even get a fresh coat of paint when the door was put back on. 📮 #postboxsaturday #PostBoxDiary

Large red EIIR pillar box that has been converted to a solar powered parcel post box. In the background is a large pub, Prince of Wales, which has a working clock at the top of the building.

Another solarfied (apparently that's not a word). For the clock fans amongst us, yes that was the correct time. 📮 #postboxsaturday #PostBoxDiary

Red rectangular posting suite. On the left hand side is an aperture labelled First Class. In the middle is a cash operated stamp machine, that is no longer working. On the right hand side is an aperture labelled Second Class.

It may not be pretty but back in the day it was a good practical posting suite - first and second class posting apertures and the option to buy stamps. It is still in use but the option for buying stamps has long gone. 📮 #postboxsaturday #PostBoxDiary

Red pillar box on a grass verge. It has the cypher of King Edward VIII.

Apparently the trend is to post what you were doing in 2016. Well, I was taking photographs of post boxes of course. I'd genuinely forgotten about this Edward VIII pillar box in Sussex. Always worth looking back through your post box photos! #postboxsaturday #postboxdiary

A red GR pillar box needing a fresh coat of paint. Behind it is a boarded up door with 'THE SOURCE OF THE SOLUTION' stenciled on it.

Happy New Post Boxing Year! I don't know what 'The Source is the Solution' refers to but I would suggest a coat of paint and bundle of letters in the post box would be a good start. 📮#postboxsaturday #PostBoxDiary

Two photographs of the same red pillar box. On the left is how the pillar box was in use. It is an EIIR box with a flat 8in aperture. On the right hand side the door has been removed. The box is covered in red plastic and the notice on it says it is out of service and an automated service is coming soon.

Will it or won't it? This pillar box is supposedly awaiting conversion to an automated solar parcel box but it has an 8in aperture rather than a jutting 10in aperture. Perhaps the original door will just miraculously appear back on it! 📮 #postboxsaturday #PostBoxDiary

I always get excited when I spot a post box - even more so when it has my favourite manufacturer's font on it! 📮😍 #postboxsaturday #PostBoxDiary

Inside view of one side of a Type C pillar box. It shows how the letters go into a cage and then the sack can be put in the bottom to collect the letters when they are released.

I was out with my post boxing pal when we arrived at this post box at the same time as the postie. We asked if we could take a photograph of the inside as we were members of @lbsg1976 and we were having our AGM around the corner. 📮 #postboxsaturday #PostBoxDiary

Red George V pillar box with peeling paint. It is next to an electrical junction box painted with a green fantasy style face.

Close up of the pillar box showing flecks of bright paint underneath.

At first glance this is just another shabby looking George V Type B pillar box, but that shabbiness reveals its past as a blue Airmail post box! One of the failed post box experiments from the 1930s. 📮 #postboxsaturday #PostBoxDiary

Pair of red pillar boxes with the front of the boxes facing away from each other. Across the road is the tower of Derby Cathedral.
