American artist Vicki Sawyer has built a devoted following from a quirky idea: "If birds can build nests, then they could make hats!" Bone china mugs hold 13.5 ounces, 4" high. Dishwasher and microwave safe. Set of four mugs includes - "Sweet Pea," the badger; "Garden Alpaca," crowned with carrots and onions; two birds on a "First Date"; and "Sully's Party," with feathered friends in fancy hats. Each mug arrives in a matching gift box.
