Fantastic! A bit of pop art here, not intended to be completely serious. I hope. Alpha Beta operated between 1917 and 1985. Wikipedia:

Before Alpha Beta was the name of a store, it was the name of a marketing concept used in grocery stores founded by Albert and Hugh Gerrard; it referred to organizing the groceries in the store in alphabetical order. The Gerrards applied this idea to their flagship grocery store, Triangle Grocerteria, in 1915.

They're all gone now, folded into the Ralphs brand.
