Hello

I saw this on Ebay as well and I would suggest the paper was overlaid on a "bigger" Harry Gilzean original Drawing, and a "poor" attempt at tracing the image ensued, making a smaller , more compact copy.
Its actually a very poor attempt at copying Harrys work (something I tried to do for years!!!!), probably by a youngster, looking to do a drawing for his own scrapbook.

Probably wasnt worth the Postage.
GGTTH.
