This is a very nice vintage porcelain invalid feeder / baby nursing cup. It is in Blue Onion pattern. The bottom is impressed with " Germany 3617". Approx measurement is 6" long by 2.25" wide, and 2.25" tall. Overall in excellent condition except a tiny chip at the tip. (I am not sure if this is even an imperfection from the factory) and a hairline crack on one side. Great additional to your vintage medical collection. Thanks!
