Boy Heroes: Terror In Transylvania
Kid heroes were all the rage in the 1940s, especially during the war years. Simon and Kirby came up with Boy Commandos, Timely had the Young Allies, and Harvey Comics had the Boy Heroes.
I'm sure there were a lot of kids during that period that wished that somehow they could be part of the war, could help defeat the enemy. The comics provided a great fantasy outlet. Some of these kid groups stayed around for a time after the war, but didn't last much into the 1950s. About the only kid group that was published during the 1950s I can think of is Simon and Kirby's Boy's Ranch. That's off the top of my pointy little head. I might be missing someone, and I'm sure one of you will let me know if I am.
This is the only Boy Heroes story I've read, and don't know if it's typical, but it's fun, golden age style: slam-bang action, exotic locale, bad Nazis, tough kids.
I thought at one time the art was by Al Avison, but I think the timing is wrong, because Avison was in the Army at the time. It was by someone using a Simon and Kirby style. There were several artists using that style either because they had worked with Simon and Kirby or because their editors told them to draw it that way. The Grand Comics Database guesses it might be by Louis Cazeneuve, with a question mark.
