Cor!! only lasted for four years but it's well remembered by readers who bought it in the 1970s. The second launch of IPC's new humour line (after Whizzer and Chips), issue 1 was published on 30th May 1970 (although advertised as 1st June). Before that though, it was announced in other comics. The half page advert above, sharing space with paid ads, appeared in Tiger dated 23rd May 1970 (on sale 16th May 1970).
A week later, this four page ad appeared in Tiger dated 30th May 1970 (on sale 23rd May), revealing a little more (but not much) about the new comic. (Click on the spread to see it larger.)
A week later, on 30th May 1970, Cor!! was launched and another four page ad appeared in its companion comics. This one from Tiger dated 6th June...
The ads were no more than teasers really, but it was enough to secure Cor!! a stable readership. (Ads appeared on TV too, long gone now perhaps.) Here's the cover of the actual first issue, drawn by Mike Lacey...
