Is anyone familiar with this artist's work? I've had this watercolor print for a long time and can't figure out if the signature is written and not part of the print. He often signed his prints. The only way i know of is to lick my finger and try to smudge the letters. That doesn't sound like a very good idea to me. Plus, it's in its original frame from 1965 complete with the Sears, Roebuck & Co. sticker, even though it was printed in Holland. I hate to rip the paper off just to see what's going on back there. It's not even torn after all these years. Any suggestions?
