Have you seen "Kimbo" 26 x 30, Oil on Canvas?

We are looking for this 1991 painting of "Kimbo" 26 x 30, Oil on Canvas.  In September of 1991, John had an exhibition at the Red Piano Art Gallery in Hilton Head, South Carolina.  We think the painting was part of that exhibition but do not have any documentation.  If you know it's whereabouts please email [email protected]
