Set of four 5" x 7" 3-color screen printed postcards with a 1-color print on the back. These are considered oversized postcards, so they will require a First Class stamp (currently 55 cents) if you are going to send them through the USPS. You could also frame/hang them as small art prints—there's literally no rules here.
These were printed at Bloom Press in Oakland, CA, by my good friend Nat Swope.
