Do you know who this dog is? - Page 1

I was just looking around on ebay for some german shepherd stuff and found a gorgeous painting of what appears to be a schutzhund working line from some time back?? I really have no idea with the old dogs, but do you know who this is? If it's one of the great dogs of old i might have to buy it. lol! The auctioneer said this:

"Up for your viewing and bidding pleasure is a signed, framed and matted, vintage drawing of a very handsome German Shepherd dog entitled FRITZ. Fritz is wearing an elaborate collar and appears to be a dog of some importance. Ver nice detail and coloring. Drawing is signed by Julian ?(fingtan)?  I cannot tell what the last name is. I have not removed the back, as it is glued, so I do not know if there is more information on the back of the drawing. Frame measures 17” x 13”, matted to about 11-3/4” x 8-1/2. Wire hanger on back of wood frame. Drawing, matt, glass and frame all in very good condition with no flaws to remark on.

I have that print and have always wondered about it. I can't read the name of the artist either. I purchased it about 6 years ago at a local antique mall. Mine is not matted and it is in a more elaborate frame. I think I paid around $65 for it if that helps you with your bid. 

 I hope someone can tell us about Fritz.
