This is an older thread, but
this is the Camino map I have at home. It shows most of the Camino routes in the North of Spain (Norte, Primitivo. Frances, etc). It also shows the Camino Aragones.
It is detailed enough that it even shows the small villages along the way, like Maneru to the west of Puenta la Reina. The lettering for the labels is easy to read, and it makes it easy for folks at home to mark progress with pins.
The map is a thick plastic and it is rigid. It is about 31" / 79 cm long x 9" / 22 cm tall. There is a similar smaller version in flexible vinyl that comes rolled in a tube. This bigger version does not roll up, or fold.
I mounted mine to a foam board which hangs on the wall. the foam board allows pins to be placed on the map without putting holes into the wall itself.
I picked up mine in Burgos at a souvenir shop in 2017, and it was used to follow my progress in 2018 when I returned to
Camino Frances. I also saw one when I was in Santiago in October at a souvenir shop. Besides the link above, I have seen them on Pinterest and on Ebay as well. Just be aware if you want the larger size to look and make sure it matches the dimensions of this one. If you want the smaller vinyl version, it looks just as detailed, but in a smaller scale.
