Roy Thomas actually tried to give the
YOUNG ALL-STARS series a progession over a 5 year period of the series that approximated something resembling the real time of World War II. Although the series was cancelled before it got there.
If you're interested in a more nonfiction account of W W II, there was a book I saw and wish I'd picked up (I
always regret later not buying)
World War II: Day by Day, an oversized hardcover with lots of newsclips and photos, that follow the daily news of World War II each day for the duration of the war, just as someone living through the period would have seen it. I thought it was a pretty cool idea of how to format a book on the subject. And would be a great reference to any JSA writer portraying the period.
I have to admit, a big pull for me was the art of Brian Murray and Michael Bair, mostly in the first 10 issues. Whose styles naturally gelled with, or consciously mimicked, or both, the better Golden Age linestyle and page layouts of the 40's era, which added to the series.
Thomas, Bair and Murray (along with many other artists) also did many single issues of
SECRET ORIGINS (late 80's run), in roughly 25 of the 50 issues, giving origin solo stories of JSA characters during the same years.
For anyone familiar with YOUNG ALL STARS and INFINITY INC, and craving more, who wasn't already in the know.
