Art prints

I have two framed prints. Livre de corbeilles Et vases de fleurs. The company that framed them was established in 1886. The phone number exchange listed on the label is 2-5466. The framing company is out of New Jersey. Is there another way to tell age/value of prints without tearing the paper backing?
Any insight is so appreciated. Thank you.

I suspect that they're reproduction prints contemporary to the frames which look 1930-1940ish. As reproductions, value would be decorative. You can confirm by comparing to an original posted above, verifying dates of framer's telephone number and address on label and, finally, opening them up and examining them to see if they are indeed hand colored and what paper stock they're printed on.
