CAPTAIN AMERICA's publishing history dates back to his first appearances from 1941-1949 in the Golden Age. After a break in publication and even though it had been firmly established that Captain America had disappeared at the end of WWII, there was a short-lived revival attempt in 1953-1954 of the character in YOUNG MEN [1953] #24-28, CAPTAIN AMERICA [1954] #76-78, and MEN'S ADVENTURES [1950] #27-28. These stories were clearly set in the 1950's. The next time the character would see publication would be in his Silver Age revival which incorporates his 1940's stories and disappearance as backstory, leaving the 1950's stories in their entirety out of continuity and stranded out of official canon. The Captain America of the 1950's stories officially became a distinctly different character than the Steve Rogers of the 1940's and the Silver age revival through retroactive continuity (retcon) changes in 1972 via the storyline in CAPTAIN AMERICA [1968] #153-155. In continuity and in canon now, he is known by several aliases such as 'CAPTAIN AMERICA IV' (although this numbering has been clouded by other retcons), 'Captain America of the 1950's', the Grand Director or Captain America (William Burnside) (this name introduced in 2010 in CAPTAIN AMERICA [2005] #608).
