|SUPERMAN and related characters copyright DC COMICS|
I've read that SUPER DC came out in June 1969 and lasted to July of 1970. That may be true (in some parts of the country anyway), but it's not the whole story. When I bought issue #1, one of the trio of free gifts was a 'wristwatch calendar', consisting of three adhesive strips (one month on each) to be applied to the strap of one's watch. The months on my calendar labels were that of November and December 1970, and January 1971. Not that they were any good to me, because I didn't wear a watch then, nor do I wear a watch now. However, this fact tends to indicate that, at least in Scotland, the first issue didn't go on sale until September or October of '70 at the earliest.
