Gorilla Lamp With Vintage Pyramid Metal Blind Shade

This is a working lamp that I believe is made of chalkware,because of the nicks & wear that is consistant with chalkware. It is not broken anywhere.I have never seen anything like it.It is hilarious, & absolutely a conversation piece, since I moved it into my den after my father passed.I have been told that yrs. ago carnivals gave prizes that were banks like this, but there is no slot on it to put a coin into.  I would appreciate it very much if I could find the history & value of this. Thanks.
