Berthet / Grenson / Renaud / Xavier - 4 Offset Print

4 fantastic prints, all signed by the artist and numbered identical: 62/200
Each print is 60 x 40 cm.

Bethet (Poison Ivy. Pin-Up, Femmes Fatales, Lloyd, Le Privé d' Hollywood) - 2008.
Grenson (Niklos Koda, Carland Cross, XIII Mystery, Le Partage des Mondes) - 2009
Renaud (Jessica Blandy, Venus H, Crotales) - 2004
Xavier (Crusade. Tango)- 2011

Since I have little experience with prints, I don't know if this is a Silkscreen, a Giclee, or how it is called.
All are on thick paper though, large, and hand-signed & numbered.
