After school of Andrea Mantegna (Italian, Isola di Carturo 1430/31–1506 Mantua), The Adoration of the Magi, ca. 1475–80. Engraving, Plate: 14 x 10 1/2 in. (35.6 x 26.7 cm). Harris Brisbane Dick Fund, 1925; 25.2.30 © 2000–2016 The Metropolitan Museum of Art. 

This engraving, known only in this incomplete state, is one of the earliest unfinished prints to have survived. It reproduces, on the same scale, the right-hand portion of an important painting by the artist, and its odd cropping suggests that a fuller composition may have been originally intended. We do not know why impressions were pulled even though the print was incomplete, but perhaps Mantegna's fame made them attractive to collectors. 

This work is exhibited in the "Unfinished: Thoughts Left Invisible" exhibition, on view through September 4th, 2016. #MetBreuer
