On the back is the authentication one is 171/365 the other 160/365. The artists signature is printed by himself, unfortunately, can't read his writing well, but, my mother said it was JEAN PAUL NOYER, (if the last name is not noyer,it looks to me like loyer or loya- also the first name seems scribbled,it could be dean paul noyer or loyer or loya. I would like to sell these at a fair market value, collectors guild apparently moved or changed names. Could you give any infor on the value or refer me,also as said the name is scribbled it could be dennis paul noyer, or dennis paul loyer. Please help must sell. Lisa
