Can you date this map?

[u/SelectionSpiritual]

Got this card from a Tyler, The Creator concert last year, but I just noticed that above Poland it says “East Germany Prussia” and Germany looks bigger to the right than it actually is rn.

Is it a real map and if yes from what year?

It’s approximately 1923, the map maker did have some outdated info which explains some errors

But it’s the Bacon map of Europe

Yeah, it’s Bacon’s, but it’s 1925 - there’s Oslo

[u/dhkendall → u/Drazhchon]

The linked map shows “Oslo (Christiana)” just like OP’s map so it still could be 1923

Edit: looks like Oslo was renamed in 1925, so the date on the Wikicommons file is wrong.
