Bears the official seal of approval of The Van Gogh Museum in Amsterdam, Bag is packaged with a packet containing a certificate of authenticity a Van Gogh biography a self-portrait, and the painting that the piece was based upon bearing the provenance of the painting on the reverse side.

 For this study in oils, Van Gogh used a small plaster model of a horse. He was then studying at the Antwerp art academy. There drawing was taught with the help of models like these, but painting had to be practiced at home. He painted this little horse on cardboard instead of canvas, because that was much cheaper. The model was preserved by the Van Gogh family through the years. It is now part of the Van Gogh Museum collection.
