3 Campbell soup kids aviators framed and double matted, Zeppelin, single and bi-winged plane.These are very unique framed and double matted pieces which definitely look to be from the mid century, circa 1950 - 1960. If you look close at each picture you will notice there are seams but I have no idea why. I was so intrigued that I had to take one out of the frame to get a close look at one of the pictures. After doing so I found that this one was glued to a blue colored stiff backing like a thin cardboard. However, it still did not help me figure out why it was glued like this in sections but it does seem as if there is one piece which was missing and the background coloring is on the backing board itself (left center section of the large one). So, maybe the same picture is underneath? The one thing I do know is I cannot find anything like it on the internet and believe these may be totally unique pieces which is part of the reason for the high broad range estimate.

Good
