Need Help - Searching for any photo of Bob Saunders

I am looking for a photo of Negro League pitcher/outfielder Bob Saunders. Does anyone have any ideas where I might be able to locate a picture of this gentleman? A team picture where he is identified would be fine. Will pay $$$, thank you.

He played for:
1926 Kansas City Monarchs/Detroit Stars
1927 Cleveland Hornets
1931 Atlantic City Bacharach Giants
1932 Monroe Monarchs
1933-34, & 1937 Memphis Red Sox
1934 Louisville Red Caps
1935 Detroit Stars

Robert L. Saunders passed away February 12, 1983. No next of kin listed in Seattle Times obituary (though it's strangely listed twice 2/17 & 2/19). Nothing else in the Seattle Times, only his name.

He was born in Roslyn, Washington Jan 6, 1902. His grandfather was killed in a Roslyn mining accident, October 1903. His family then moved to Seattle. Pitched for Franklin High School though he is not listed as a "notable alumni". I believe he may have been the first African American to play baseball for University of Washington (1920-24?), but he is also not on the roster when I went to fanbase. There is a taped interview with him at UW library (1968) about negro league baseball and integrating the local stevedore union. Two hour drive but what the hell. It will give me a chance to comb through the old yearbooks.

Still looking for a photo, thank you.
