Scholarship Says No.

I got a call from a museum asking if I had any data on black artists, who worked in Colorado from 1800-1960?
I looked through my reference library and found that there's was no record of artists who are black for that time period.
If there were any, there's no record of them.
my study in this time period, shows that there was no interest or support for black art makers.
I do have lots of information on black artists nationally.
