A. Dear C.W. Sttenberg,
I'm sure that this was an oversite and I would recommend having these sent back to have signed. If you would like, I will contact the publisher on your behalf.
Please Email me directly, with the name of the business you purchased the print, the number of the print, and I will determine the best procedure to proceed.
Value? Without the signature, it's really missing something, however without the signature, it's really missing something! :-)
