Mortimer M. Clark

Here's a picture of one of my relative's (my 3G Grandfather actually) who I believe was born in Cleveland, Ohio. (Mortimer married Frances Marian McGLASHAN, daughter of Robert Peter McGLASHAN and Sarah HOLMES, on 19 Aug 1862 in Oronoco, Olmsted, MN). He died 20 Jun 1911, in Alberta, Canada

This is an approximately 2" x 3" metal sheet with picture on it. Is it a tin-type? I really don't know. I've got a much higher resolution copy if anyone's interested.
