For an Aubusson tapestry to be an original work of art, every model is limited to 8 copies, numbered in the weaving as E/A n° 1 or E/A n° 2 and from 1/6 to 6/6. The initials of the workshop and signature of the artist are also woven.
Each tapestry must be accompanied by a certificate of authenticity bearing its name, registration number and dimensions, the initials of the manufacture or workshop, as well as the artist's signature. Lartigaud Jean-Michel.
