Singing Birds, Northwood   Updated 1/31/2009
Singing Birds differs from Imperial's Robin in that the birds here are framed by panels. Northwood's own Springtime pattern was made in some of the same shapes as Singing Birds and has some of the same features--including the panels. If it has a butterfly and basketweave around the bottom, it's Springtime. Note that reproduced Singing Birds tumblers have been found in amethyst, aqua opal, cobalt and ice green.
