I recently bought these two strips on eBay. Both are by Fred Ray and signed "FRAY".
Notice how he uses light and shadow just like Noel Sickles did. And, yes, he was a big fan of Sickles. It was from Fred's collection Alex Toth and some other artists got their Schorcy Smith sets a long time ago.
I suspect these were drawn while he was doing his military service during the early/mid 40's. But does anyone know where these were published? If they were published at all. They seem to be aimed to people not in the army since they explain how things are in the army. If you have any clues please leave a comment.
[Edit: As a bonus here is the third strip that was sold at the same time. But I didn't get this one.]
