Following up earlier posts about the sad state of Detroit, I’ll balance them by noting that we do have one of the country’s finest art museums, with a vast and varied collection. Today, I read that we have an artifact I never knew about - Custer’s battle flag from Little Bighorn - and it is going up for sale. This isn’t a bad thing - the flag is rarely here, and it’ll bring in serious dough for further acquisitions. It’s just an indication of the richness of the collection itself, a bright gem in an increasingly bleak landscape.
