I think this vintage bright yellow pitcher is Bauer Ringware. It isn't marked, but has the Bauer look, and there are a lot of similar (almost identical) shapes showing up with a google search. It measures 4 inches high at the tip of the spout, a little over 5 inches from the spout tip to the edge of the handle, and 2.25 inches wide across unglazed foot ring.

The pitcher has a lot of crazing, particularly visible on the upper half of the exterior (around the rim and upper rings, where it has darkened). There are also pinhead-size or smaller fleabites (shallow chips or flakes) on the rings, visible in the closeup photo. There are also a few rough spots around the foot ring. The bottom isn't marked.
