My mom obtained several small appliances with those stamps. One is an old electric mixer from about the late 1950s. I inherited that mixer. Not fancy like most of the mixers today, but it still works. Almost solidly stainless steel. Weighs a ton, but it does the job.
I remember rA& P. I vaguely recall my mom collecting Green Stamps.
Several years ago the one by me became a Stop & Shop.
Then it was closed an a Super Shop & Shop was built.
In place of the old supermarket became a bargain clothing chain, and a chain that sells things for a home. They closed and if was knocked down. Now it’s just - nothing, .
