Vintage School or Camp Logos

[flat-top]

I'm on the hunt for vintage school or camp logos from the 30's-50's. I have a vintage style sweatshirt that I want to print a cool image on. I can't find any images online (that aren't already on repro sweats!).
Can you guys help?

I ran a quick search of my high school alma mater, and found a couple vintage images, the logos from the different graduating classes. I suggest you try the same?

That camp shirt looks more like a graphic artist design than an actual camp logo, to me at least.
