A few months ago I wrote a post about a leaf at Houghton Library, with a miniature of the Baptism of Christ on one side and a Beatus initial on the other, in which I identified it as one of the leaves sold anonymously by Gustav Nebehay at Sotheby's in 1926.
Only later did I realise that this conflicted with the account of its provenance as published in 2010, which implies a direct line of ownership to Houghton from an auction in 1912, with no mention of the 1926 auction:
"Sold at auction in Munich in 1912 to Edgar Huidekoper Wells (1875-1938), it was acquired by George J. Dyer for the Fogg Art Museum (1927.21) before being transferred to Houghton Library in 1990"with a footnote detailing the 1912 auction: C.G. Boerner, Leipzig, Auction CX: Manuscripte und Miniaturen des XII. bis XVI. Jahrhunderts, Handzeichnungen des XV. bis XVII. Jahrhunderts, Versteigerung ... 28. November 1912, lot 15; the image above is taken from this catalogue.
