any Marc Chagall fans here that can help me with this litho  

Nice! It is actually called "Le bouquet clair".

It is not in the Chagall books I have but you'll find a few exemples if you google the correct title.

Two inexpensive but invaluable items to help the untrained determine authenticity of fine art prints:

"How to Identify Prints" by Bamber Gascoigne - $25

Cheap illuminated pocket microscope - $12

A no-brainer investment for anyone interested in the subject.

As for your print, del, authentic Chagall lithographs were printed from stones. Under magnification, "offset" lithographs will show a pattern of tiny spots of color and would indicate that it is a reproduction.

I had searched that but the coloring is different. The one I had linked is the only exact one I have seen, with color strength

Any thought on the close ups?

There is also a light pencil $80 marking on the back that quite Worn away. The lady I got it from didn't know about it. Does anyone know what where original sales prices of these back in the day? 80$ in 1970 is about the same as 500$ today. It came from one of the islands around Savannah GA which are very wealthy and have a high Jewish population. So not sure if there is any Legiticy to my theory

And I did use a magnifying glass....or in this case my watch lope.

I know some basic knowledge with lithos watching/helping friends do some back in art/design college day. There isn't any consistent dots like you would see from mondern day print..

If the signature is printed or "stamped" onto the paper, it's a repro. And it's likely faded.

Anything written on the verso is highly suspect.

Here is a close up

Here is a close up. I can't seem to edit last comment. This forum platform never works For me

I also have a Chagall stone litho that I have had for a while. It's different in that it has the sig as part of the print

Mine is weird in that the colors slop all over the edges. I think it's cool

and here are a couple of LINKS since posting pics is problematic.

OK, so, I was mistaken about signatures. Apparently many Chagall prints show them integral with the printed design or "in the plate". Many, but not all, are also hand-signed and numbered, usually in pencil. There are many factors contributing to authentication and/or value.

I can't tell from the photographs if the prints are authentic or not. If, under magnification, the prints don't appear as if produced by photomechanical processes and all else about them seems consistent with originals, then they might be worth having appraised by an expert. Chagall was extraordinarily prolific and his prints were very popular. There are, as well, tons of fakes and reproduction prints out there, so it pays to be wary.
