Remember Libby's corned beef hash? (1971)

 Once upon a time, there was some competition in the marketplace for corned beef hash.

In addition to Hormel's Mary Kitchen brand, you had Armour, and, in this next item, Libby's. I've personally had Armour & Mary Kitchen, but the Libby's hash was off the market by the time I started doing my own shopping.

Roger Bowen ("M*A*S*H", later of Arnie) sports the Libby's sweater, conducting a pre-Brady Bunch Robbie Rist.
