Questa mappa in un libro di testo ceco mostra il Vorarlberg come parte della Germania lol

It also shows the borders in Lake Constance wrong (as in that there are borders).

Brandenburg and Saxony-Anhalt have weird shapes, too.

Bremen and Saarland have open escape routes into their surrounding counties.

Sachsen-Anhalt also got a random chunk of southern Brandenburg there lol and Bremen got skipped completely
