They should be around the country in ArtOMat machines shortly. They are small- 2 x 3 inches. More of a promotional item than anything, as they do take quite a bit of time to make. Print and trim the prints, drymount them, apply three coats of varnish, sign the backs, cut and score the easels, pack them in their little boxes, apply the labels and cellophane, and ship them off. They really are quite the bargain as they sell for $5 in the machines.
