Yeah, it's kinda wrong. It's just two pieces of salt pork. At this point in time, refrigeration did not exist so pork would spoil and become deadly within hours of slaughter. It was illegal to sell raw pork products in many countries because of Trichinella, so if you were eating pork it was either charcuterie or salt pork.

Industrial scale farming and modern refrigeration only really made raw cuts of pork widely sellable in the 1950s.
