It is a very heavy plate and is 14 1/2 " in diameter.  It has blue etching around the rim, and a flower patch medallion inset in the middle which looks to be ceramic.  The rest of the platter feels like Bone China with a cross hair pattern that gives the platter a sort of  bamboo style look. I have not been unable to identify the signature.

This is an Anheuser-Bush, First Edition Americana Series commemorative plate.  Cast in 1972, this Sterling Silver plate is No.620 of a limited 5000 run.  It is called "The Clydesdale Horses and Stables," and includes a certificate of authenticity as well as a silver medallion all in excellent condition, tamperproof, elegant, original framing.  Thanks, Jeff

Ive found out that this creamer is English,but would really like to know what the stamp is and who the maker is. Im told its late 1800's to early 1900's.
