Studio Pottery Vase Blue Crystalline Flambeau Signed Campbell ?

Height - 8 1/2” Full width - 5” Condition - excellent condition, no flaws. Signed; I have received mixed “confirmation by Bill Campbell experts”. Several agree it is a Bill Campbell early work. One individual worked in the studio with Bill since 2012. These are her comments on the flat bottom and odd signature. “You have a vase pre 2014. The vases before then either had the signature in the mold, or an employee would put the signature in with a stylist. It looks to be a saki vase and usually a small bottom would not work well for the signature to be in the mold. You would have had to see him sign it if not it most likely was an employee who signed it. When I started working there, we were taught how to do his signature on the bottom of the pieces that didn’t have it already in the mold. Later, when he was giving a tour said that us employees could sign our own checks if we wanted to, so that’s when he decided to start using the stamp.”. Many agree it’s a Campbell; some disagree. It is beautiful and very well crafted in any regard.
