One of the items, lot 36, in Sotheby's Continental and Russian Books and Manuscripts Auction (Sale L08403) in London tomorrow, July 8, is a copy of Stephens' third edition of the Greek New Testament, printed in 1550, formerly owned by Bruce Metzger among others.
On the same day, in the Western & Oriental Manuscripts Auction (Sale L08240), a papyrus fragment with Septuagint Psalms 70 and 71 , which formerly belonged to the private collection of the Austrian conservator Dr. Anton Fackelmann (1916-85) is offered.
Update: Thanks to Wieland Willker who noted that the text of the fragment is LXX Psalms 69-70. Sothebys apparently has the wrong information.
Second update:The Stephen edition was sold for 3,250 GBP, and the papyrus fragment was sold for 17,500 GBP.
