Showcase Presents Our Army At War 1
I think this is the earliest material DC have reprinted in a Showcase volume – it starts in 1952. I guess this is partly because that’s where the series started, but the fact that it doesn’t look Golden Age must have helped the decision – the standard style for war comics doesn’t seem to have changed so much, and bar the odd racist exaggeration of the Japanese enemies, a lot of this would hardly look out of place today.
