|I recently got it into my head that I wanted to collect mouthpieces. Not just any old mouthpieces, but pieces owned and played by famous players. So far I have a grand total of one mouthpiece! I'll not mention that player's name because I don't want him inundated with requests. So, does anyone have any pieces that would go in my collection? How much do you want for them? The problem I foresee is establishing provenance. The one I have came directly from the hand of the owner, so there's no question. But what if someone says they have a piece once owned by Louis Armstrong or Al Hirt? Can you prove it?
