Was told this was a Fentn Bowl...cannot quite make out signature

This is a really beautiful art glass bowl which we purchased in a little town in Colorado about 10 years ago. The lady was closing out her store so we purchased this and 2 other pieces. The irredescence is really wonderful and the colors are beautiful in general. It's a generous size at 3" x abou 8.75". If it's not against the guidelines I would really appreciate anything anyone could tell me about this piece. I'm not a collector of glass and cannot quite read the sigature. And I have to go by the seller's word that this is Fenton at all. Thanks for any help. Pat
