What is approximate value of floral painting on hard board by M DeCamp? This belonged to my parents who were married in 1935. There are no tears or chips on the painting which I assume is oil painting or some similar hard paint.

Have you considered an art appraiser?

No way to even guess at a price of a painting. Look on eBay, there are some on there. From the postings, he? Did florals. Whatever the posting price, there are no bids so, at this time, the value is $0.

Probably Maurice Alfred Decamps that sells from a $100 to a few $1,000s. Without further ID it's impossible to really know as said before.
