The Portland Stamp Company The Portland Stamp Company

The Artist Series

An ongoing collaboration with invited designers, artists, and writers who create original work for an unusual form: the poster stamp. The sheets are signed and numbered by the artist, each in a limited edition of 100. All stamps are printed on lickable, gummed paper and pinhole perforated by hand on our vintage machines.

We release new Artist Series stamps monthly with announcements in our newsletter and on Instagram.
