S&H Green Stamps were trading stamps popular in the United
States from the 1930s until the late 1980s. They were distributed as
part of a rewards program operated by Sperry & Hutchinson. This
sign, like our Woolworth and Rexall Signs, has an additional set of
contacts on the back for flush mounting the sign to the front or side
of a building. Our S&H green stamps sign is the perfect companion
to our window sign version that can be seen HERE.
