16x20 on canvas backed fabric
Text on the top left corner says "Gecko". On the right it says "Aboriginal Art Australia" and in the lower right it says John Smith Gambula
I'm not sure if it is an original acrylic or if in fact it is a silk screen or something else. You can definitely feel the texture of the paint on the surface and the signature looks right. Who knows, it may not even be authentic. Perhaps it was made for the tourist trade with that "Aboriginal Art Australia" in the upper corner.
I tried to find out more about the artist online. I did find a couple of similar works by the artist. This is about all I came up with about the artist himself. In Brisbane, Queensland, painter and glass craftsman John Smith Gumbula is an artist much in demand. He is currently finishing a major glass commission for the new Criminal Justice Commission building on Creek Street.
Patricia, a blogging friend who frequently posts here, lives there and is well connected in the art community. I'm hoping she will have something to add to my knowledge.
In any case, I paid $5.00 for it and I'm delighted. Now I need to find the right frame.
