Copy after Teniers

At Lempertz, 16 May 2015, they sell a "Flemish Master, late 17th century" Temptation of St. Anthony, estimated at 5,000 to 6,000 Euro.

No indication is given of the fact that the original hangs in the Louvre, and is by David Teniers II. It obviously is the same composition, but the Louvre one is more finished and detailed, even though it is at 22 by 16cm a bit smaller than the one for sale, which measures 36 by 27,5 cm. It is a good copy, and may be by the Teniers Studio (it certainly is vastly superior to the dozens of Teniers style paintings for sale every month), but it is strange to see no indication of its source at the auction. UPDATE: sold for 10,540 Euro, twice the estimate.
