Red Skelton Clown Lithograph 1972

I found this lithograph at a local estate. The owner said there grandpa was an artist and new alot of famous artist...this litho belonged to him.

The paper it is on has tiny tiny little squares...almost looks like what they make a cast with when you break your arm. (i am probably wrong but I think this may be called canvas?).

It is signed Red Skelton (looks like a print of the signature). Dated 1972.

Does this have any value?
thanks
