This is a vintage Norcrest bird mug, designed to resemble a hollow tree trunk with a branch-like handle. It features a charming yellow bird peeking out from a knothole framed by green leaves and red berries, giving it a whimsical woodland feel. The mug is hand-painted with a glossy glaze, typical of mid-century Norcrest ceramics, and is a collectible piece often found in their popular “Bluebird” or “Forest Friends” series from the 1950s–60s.
