Peacock and Dahlia, Fenton
Fenton used this pattern for their classic era glass as well as in plates made for the 1991 Heart of America Carnival Glass Association convention souvenir (in red). However, here it is as a 6-inch ruffed sauce in marigold, apparently made in 2000 as it is marked with the oval "F" and number "0." Thanks to King Hoppel for the photo.
In 2016 this red Peacock and Dahlia tricorner bowl sold for $35.
