I hang around on a few mailing lists and in a few groups, and usually I just lurk in there and read most of the posts. Sometimes I wonder whether it would not be a smart move to unsubscribe from most of those groups and lists, since I don't participate much and since there's often chatter that I find distracting. And then, once in a while, a real gem comes up that makes me glad again about my subscriptions.
A few days ago, such a gem turned up on the 75years mailing list, a list focusing on the years 1250-1325. In a conversation about SCA baron titles (which I almost didn't read, since it falls under "chatter" for me), Michael posted a link to his flickr album with pictures from the St. Louis shirt.
In case you do not know about this shirt, it is said to have belonged to St. Louis and is nowadays in Paris. There was a bit written about the shirt by Dorothy Burnham, but as far as I know, there is no in-depth research published yet.
As Michael writes in his post, the shirt is in the Notre Dame museum, on display and quite easy to see - and no-flash photography is permitted. That is what he made good use of. You can see the photos here on his flickr page - and thank you very much, Michael!
