Billhaven, thanks for that info. I was wondering specifically about the Sondheim-signed sheet music. The pre-estimate was $500-$800, which seemed way too low based on the bids at the Broadway Flea Market. I was expecting it to be at least $2500, but $7000 doesn't surprise me that much. I'm guessing the estimator doesn't know that much about Sondheim. I wonder if one of the auction houses specializes more in theater stuff.
