Trying to locate a painting I saw in a Shriner's Children Hospital. Cannot read the artist's name. Looks like Robert or Roberta and the last looks like Gu---.

It has three clowns sitting on stools and they are all laughing. Looking at the picture, the clown on the left is in a dark suit facing his left and two clowns in white.

Tried to look at the back of the picture, but it was just canvas. Checked with the administrator and he said the picture was there when he came.

Any help, suggestions or directions is greatly appreciated

Looking it up I found these sites
Maybe you can call them and ask. The one site seems to say they are still selling clown paintings and a lot of stuff about Red Skeleton. '

Would it be possible for you to post an image here of the painting and also a close-up image of the signature that you saw on the painting?
