A lemon layer cake on a table with the words “Happy Open Data Day or Week!” written in red icing on top. The joke is that Open Data Day is (since 2023) a week-long event, but still called Open Data Day.
Also my colleagues are wonderful and one of them bought a cake for “Open data day or week!” (with love to @okfn). 😆🍰 #OpenDataDay #ODD26
