I have a oil painting signed by R.Delongprie it is of a bunch of different plants all of green leafs on looks to be a deck floor. It's very large and is in a frame. Is it worth anything? Is it real?

Even if you posted a picture of the painting, and even with the name of the artist, it won't be easy to find any information about it online.

Your best bet is to see an art dealer, someone that has knowledge about art, and the value of that art.

I am thinking he may not have been very famous because most of what I could find on the search engine was ''Do you mean Paul?''
One person said they have a painting of owls by R.Delongprie that was appraised at 1000 dollars.
And another saying they have one of birds on the beach by R.Delongprie
