Sotheby's announced this morning that they will sell the Old South Church Bay Psalm Book on 26 November in New York. They've placed an estimate of $15-30 million on the volume.
The Bay Psalm Book will be displayed at Sotheby's New York from 12-14 April before being exhibited around the country in the coming months. From 18 November through the sale it will again be on display in New York. The press release indicates that a schedule will soon be posted at http://www.sothebys.com/baypsalmbook.
The church membership voted in December to sell the book, one of two copies still in its possession (of an original five which came to the church through the bequest of Rev. Thomas Prince).
