This is all so interesting! Somehow I'd missed this thread until the current bannering... so this is great!
As a museum type myself, I'll agree that the display looks a little crowded. But, it's so nice that the museum is treating them and the subject of BBM and the subject of being gay in the west with such respect and in-depth content. I think that's great. I'll be curious to learn more about the archive of the Gay Rodeo Association too, that Pete mentions earlier in this thread. It would be nice if that finds a permanent home. I'm curious... did any of the content address the subject of gay cowgirls... or just cowboys?
About the shirts themselves... the lack of blood bothers me more than the crowded-ness of the display case.
I'd really love to know more about what happened to the blood... since that's such a key feature in the storyline of the shirts. To me, having the blood washed away is a little bit like taking a piece of the BBM context away. I wonder what they use to make stage blood like that? It seems possible that the blood material might fade away and be less intrinsically stain-y than real blood. But, if someone actually washed the shirts... that kind of boggles my mind. I'd be curious to know if it was someone associated with the film (costume dept, etc.) or if it was the collector. Also, it makes me wonder if there were more than one sets of shirts. In filmming don't they often have a couple versions of the same costume on hand? Maybe some of the shirts were bloodless for some reason.
Also, as others have commented... it would be great if the shirts someday found a permanent home in a museum. But, they shouldn't be displayed permanently. To preserve fabric (like paper) properly it needs to be "rested" from time to time in the dark. Ideally, fabric would be displayed for several months then rested in the dark for several months and then put back on display (repeat cycle). It's astonishing how fast fabric and paper fade and change in terms of character and appearance when exposed to light for extended amonts of time.
