"Attributed to Marten van Cleve" is copy after Maerten de Vos

Hampel, from Germany, sells on 30 June 2016 an "Attributed to Marten van Cleve" Adoration of the Shepherds, estimated at 16,000 to 18,000 Euro.

The RKD lists another version of the same composition, this time said to be "After Maerten de Vos", which is of much higher quality than the one for sale, despite being much smaller (15 by 10 cm only!, vs. 92 by 49). That work is half of a diptych together with a "Carrying of the Cross" (als pictured above).

The work for sale is a rather awkward copy and not worth the estimate by a wide margin. It can at best be described as by a Follower of Cleve.
