First off, I have three scarce OoP Juggling books.
Vol. 1 and 2 of "4000 Years of Juggling" by Ziethen, mint condition. (Never dropped) :)
$750.00 the pair. (appraiser said worth $1,000)
And JUGGLING the Art and its Artists. $100.00
Thousands of photos of jugglers from the beginning of recorded history.
