Mount Clemens North Star Atomic pitcher still has great color and style!  This pitcher is 5" tall, 6" wide from tip of spout to back of handle and 3¾" wide opening across the top. This piece is marked USA on base.  
The base does show crazing (surface level cracks on the glaze only) on the outside, while on the inside, just a pattern similar to the outside crazing. There is minimal crazing around the top edge of the pitcher that is very difficult to see.
The glaze is starting to show discoloration of a light brown near the bottom ¼ of the pitcher, which is very light in color.  Otherwise, no nicks, dings, chips, or cracks are noted on this piece.
