I am rather embarrassed to ask, but what are Picnics?

In the pickpocket- honorary guest picked at random for Mayberry's Founders Day episode, there's a prominent sign on the market's window.

Was this a butcher's cut for Deli meat or hot dogs?

I believe it is a picnic ham.

Awesome!

Thanks a bunch. :)
