Tumblers Made into Whimsies  
Series 4: Dugan/Diamond Grapevine Lattice
by Don Kime

Grapevine Lattice is a Dugan/Diamond pattern.  All have very good color, especially the white. If you could find a blue whimsie, it would be very rare as few tumblers were made in blue. They were made, probably around 1914
