My other favourites from Bonham's were a lovely Jan Asselijn is estimated at £12k-£18k, a Cavallino £20k-£30k and a newly-discovered Andrea Sacchi at £250k-£350k.
Sotheby's also has a glorious early Jan Brueghel the elder (£1.8m-£2.5m; really nice little picture, but this shouldn't be more expensive than the Master of St Veronica!), a Rembrandt Head of Christ (£6m-£8m) and an interesting pair of pictures of beggars by Giordiano (£150k-£200k).
Christie's has the Eric Albada Jelgersma collection of mainly Dutch and Flemish pictures. He had some fine pictures, but his taste is not mine. More appealing to me is this Antwerp school Lamentation with an unusually horrific scalped Christ (£250k-£350k). A lot of similar pictures were painted in Antwerp, and the quality is often really good. But I wonder how many people would want to live with that rather harrowing image. More conventionally popular is a magnificent English-period Van Dyck of a beautiful young Princess Mary (£5m-£8m). Another version is at Sotheby's, given to Van Dyck and studio, but not a patch on the Christie's masterpiece.
