Well here's a good logo for Ms. Williamson's new department:
By the way, the shirt in the pic is mine.
Got it at a little music festival in upstate New York just about 50 years ago.
This is NOT "a reproduction" (of which there are thousands).
It's a REAL, genuine festival security staff shirt.
You couldn't buy these, no one sold them there.
I'll go so far as to say this one might be "the best surviving example".
