Yes, collecting Beatles tickets is great. They are real pieces of music history. I love the American tickets. I have 3 unused tickets: Shea 1966, Boston 1966 and Candlestick 1966.

Very popular...especially certain venues....Hollywood Bowl...Shea Stadium....Candlestick Park...and...believe it or not...September 12, 1964...the Boston Garden.
