I believe these to be reproductions ... the paper is too heavy and too crisp to have been sitting around for 50 plus years.
The colors are very true and the art just excellent. Nice pieces. I believe I have a couple others that didn't make it into the online inventory, so if interested just give me a call at 817.992.8220 and I will see what is in the art archives,
In the meantime, grab one of these while still available.
