Photograph of a Man with a very large Dog

This is an antique photo of a man with a very large dog, I think a Great Dane.    It was photographed by Renshaw, of 2718 Girard Ave in Philadelphia.  Writing on the back indicates the man is named Louis Haeckner, and that he was born in Germany.

We've listed a lot of photos of the Hackner's (sometimes spelled Haeckner) recently.  Margaret Hackner, who I suppose was a daughter, married Oliver Phillips, and we have a lot of photos of that side of the family.

This is an early 20th century Gelatin Silver photograph, and there is heavy silvering on the photo, so heavy that if you tilt it slightly one way or another, the silvering is all you can see.  Tilt it slightly toward you and you see a sharp photograph.   I don't know the exact date of the photo, but it is probably 100 years old or close to it.

It is an unusual studio photo - a man with a huge dog in his lap - and the type that many people find interesting.   At least I do. 

Update:  Sold!

Another Update - the dog may be a Presa Canario, not sure.
