1950s Clown Painting Oil on Board / CANIGALL

I have recently aquired a well pained painting of a clown packing up his possessions getting ready to go home (I think) by an artist called Canigall.

Could somebody please look at the painting and maybe give me some information on the artist or point me in the right direction as to where I can sell it to a clown / circus painting collector.

I would appreciate any help.

THANK YOU
