This is the advertisement for the first Lindy issue, from Jinty 14 June 1975. The ad entices readers more with a Bay City Rollers pin-up than the story contents. Only the cover gives any indication of what stories to expect. Lindy was a short-lived title and merged into Jinty after only 20 issues. She was the first of two comics to merge with Jinty.
