I found out from Carol Boss (Hahnemühle) there are dealers in the US that sell the post cards but do not list them on their websites. Silly people… I’ve been buying from Jackson’s in the UK!
I invite everyone to contact those dealers and ask them to list it on their websites:

ARTISAN / SANTA FE INC – Ph 505-954-4179
