Crystal Block Creamer which is an Early American Pattern Glass piece. I have seen this in ruby stain, but this is the first one I have seen which is clear. This was in a collection I purchased about 28 years ago. It has 4 blocks on each side connected by a washboard rib pattern and a starburst pattern on the bottom. This Creamer is 3 3/4" tall by 3 1/4" across. It is in excellent condition.
