subtitled "The Story of Motorless Human Flight" by Robert Kronfeld (1933.)

I'm told that only 500 copies of Robert Kronfeld's book were translated into english. I have two extra copies to sell someday, perhaps at the International Vintage Sailplane Meet (IVSM) on Harris Hill near Elmira, NY, July 9 - 16, 2016. I need to thin out my huge collection of vintage books and memorabilia. I'll probably publish an inventory sometime this year before auctioning on eBay.

Since the copyright is expired on these books, what would you think about scanning them and putting the .pdf on the Soaring Museum's website? Or they could sit unread and moldering in private collections.
