NEW YORK CITY — Of the more than 1,400 lots to cross the block between January 17–20 at Sotheby’s, the priciest result was $675,000 for a lot of two portraits by Joshua Johnson, one depicting Dr Andrew Aitkin, the other depicting his wife, Elizabeth Aitkin, with her daughter, Eliza. The result set a new world auction record for the artist and was tenfold the expectations for the lot, which had been estimated at $60/80,000 and came from a private Maryland collection.
