From its description, its a Portuguese-wank where the POD centers around the Portuguese explorer Diogo de Teive discovering the Americas decades before Columbus would in OTL. The real reason I picked this map, however, is the shadowing used to denote those areas unknown to Europe, which communicated a powerful message of what fate has in store for Portugal and this timeline in general.
Honorable mention this week goes to Todyo1798's "'NEVER!' A satirical tribute to Ian Paisley". If you want to submit a map for the next Map Monday, email me at ahwupdate at gmail dot com with your map attached and a brief description in the body of the email.
