If you like those cards, you might also like the LatLon notebooks from Analog: http://store.analog.is/products
Notebooks with beautiful maps in the covers using letterpress.
Prices seem roughly in line with what I'd expect for letterpress (not commenting as to whether it's expensive or not). (cc @maxisnow I hit reply but accidentally deleted your handle)
@shapob Probably true, traditional shops will have a library of plates and glyphs they can use to make cards but custom making plates and stuff can get expensive and time consuming quickly.
