I believe this is an M1 Garand .30-06. That would make the image sometime from the 1930s. The M1 was produced from 1934-1957. No other information available. Found in a thrift market in Fayetteville, Arkansas.
This well behaved youngster takes their job seriously by guarding what looks to be a greenhouse or possibly a zoo exhibit with a double-barrel shotgun. “Fritz” won’t be stealing any of our state secrets as long as this whippersnapper has a say in the matter. I’m presuming this is somewhere around the 1940s. No other information is provided on the image. Found in a thrift store in Fayetteville, Arkansas.
