Hi, my name is*****'m a certified appraiser, and I'd be happy to help.
This is a print, a lithograph, not an original painting.
Could you please upload an overall photo so I can tell which image it is? Also, is there a title on it, usually in the lower right corner?
This print, "Covered Bridge and Fisherman," most recently sold through EBTH for $9.00, framed. (That was #450/1500).
Unfortunately, Colway lithographs rarely, if ever, resell for more than $50.00.
I'm sorry for any disappointment this may cause.
