Every piece of work is signed, dated and titled by the artist and the angel 41 stamp is always positioned in the bottom left corner on the reverse of the piece (pictured here).*

All artworks are added to the angel 41 gallery which also serves as a form of authenticity. If it's not in the gallery, it's not an angel 41.

As the artworks increase in value it is inevitable that some of them may be re-sold by collectors. The artist has nothing against such transactions, but cannot be held responsible for any of these external sales.

A certificate of authenticity, which contains a photograph and description of materials used for the artwork supports every piece of art sold by angel 41. This is also signed by the artist, (see detail below).

* Works on paper are just signed titled and dated on the reverse of the piece.
  Sculptures are just signed. Street works are sprayed with the angel symbol.
