Thought I'd show this. This is a full-page ad for a DePatie-Freleng short "Hurts and Flowers", the second in the Roland and Rattfink series. It appeared on Variety on January 10, 1969.
This is very much a rarity. As far as I'm aware DFE never did an ad for any other shorts; there was a poster for "The Pink Phink", but otherwise that's it.
