“Too Pooped To Pop” backed with “Let It Rock” by Chuck Berry is one of the last rock and roll songs issued on the 78 rpm speed. Most of the later 78s were blues. This is a January 1960 release, and you can see here how Chess records was trying to use up their different labels – one with the chess pieces and one with the vertical lines.
American 78s - The Last Year 
Went to an estate sale a few years ago, and they had maybe 15 50s rock 45s, and ONE 78 – this Chuck Berry from 1960! How it ended up in western NY state, I’ll never know. Was sold to a long-searching Toronto gentleman – VG+ for around $400.
