Soooo cute and useful. I think it may be pewter, from other descriptions of this same item. This creamer even has a little bowl to catch any drips! According to Google search, "Pierre Deaux was a French inspired gift shop & catalog chain and is no longer open. This creamer set was one of the signature items." Dimensions: Length: Cow about 5¾" long head to tail. It just fits in tray. Width: Almost 3" side to side. Height: About 2⅝". Liquid amount: ¼ cup just fits. Works well. We tried it with ¼ cup water.
