On the letter page of
X-Men (I) #12 this announcement is made:
"By now, you've probably heard that mighty Marvel will be offering eight super-Annuals this summer! They include the fabulous FANTASTIC FOUR ANNUAL ('natch!), the SPIDER-MAN ANNUAL, THOR ANNUAL, SGT. FURY ANNUAL, MARVEL TALES ANNUAL, KID COLT OUTLAW ANNUAL, and the popular favorites of all adventure fans -- MILLIE THE MODEL ANNUAL, and PATSY WALKER'S FASHION PARADE ANNUAL! All kiddin' aside, those value-packed 25c gems will contain some reprint material, and some brand new stories, too -- just to keep you thoroughly confused! We're mighty proud of 'em all -- latch on to them and you'll see why! 'Nuff said!"
It seems that the Kid Colt Outlaw Annual never left the corral.
