Hello Robert,
Thank you for taking the time to look at this. No, the only mark is on this one piece of the picture. Actually there are several sections all deplicting famous romances of the past starting with Adam and Eve, all kind of naughty. It is about 10 feet long. It is sooo unusual. Everyone that has looked at it said...............wow, this is good. But no one has been able to identify the artists mark. No Litho company's name is on it anywhere. It's colorful, that's for sure, in more ways than one!!
Thanks again for taking the time Robert. I'm still hoping someone out there on this board will know!! Have a Happy Easter Day.
My very best Regards,
Debby
