Real Photo Postcard, unused. AZO stamp box.
A beautiful photo-turned-postcard of a handsome guy in profile, with white beard, in suspenders, one hand resting on hip, the other holding his straw hat and with what we might think of as the “old homestead” in the immediate background. The only identification is written on the back as, “Grandpa McInnes.” The stamp box is an AZO, two triangles up and two down, which is estimated anywhere between 1910 and 1930, per Playle’s.
