Around the faces and on the edge of the Virgin's hand can be seen traces of powder, testifying to the use of a perforated card, used to produce replicas or variants. The serial nature of production does not mean, however, that the work is of poor quality, indeed the panel has been executed with great refinement in the rather strong colours, with combinations of blue, red, yellow and white with golden highlights.
The attribution to Vincenzo Foppa is not certain, even if the panel has elements of Foppa’s style between the 1460s and 1470s.
