VINTAGE 1950's Blue Baby Carriage Planter

This baby blue beauty feels heavier and denser than others I've seen and sold, making me thing it's made by one of the well-known potteries of the early 1900's, although it has no labels and marking. It's about 4" tall and 5" long, and would be a sweet welcome for a modern baby! There is a slight void in the glaze where the handle meets the body, but rather than damage I believe it is just a place where the glaze parted in the kiln.
