Boy Comics #117 pg 4 color guide

I mainly like to get color guides for pages that I own but I couldn't pass these up. In this instance, I had never seen color guides this old or painted on silver print copies. I'd never heard of silver print copies. After checking, I found there are some older EC silver print color guides out there. This is still the oldest complete story silver print color guides that I've seen. So feel free to check out all 8 color guides for this nice little Joe Kubert drawn Crimebuster / Chuck Chandler story from 1955. If you know who colored it or who some colorists were for Lev Gleason, let me know. Thanks.
