Hi. These beautiful pieces are not signed but came with a paper that read: Dale Chihuly Pimento Red Seaforms with Tar Lip Wraps. They measure 6'x9"x5" and 4"x6"x2". From what research I have done, it seems not all Chihuly is signed, especially when it is from a series. Do you think this is the case here? I would like to offer these for sale but am unsure how people feel about unsigned Chihulys, though I would imagine if it were made specifically for the intent to defraud, it would have a fake signature to go with the fake piece, yes? Thanks for any info!
