Clear and bold stamp of WP #115 'I in a Diamond'. 

This is an uncommon mark produced by the Toyotomi Glass Company.  Toyotomi also produced the much coveted 'TO' mark.  Although the 'TO' floats come in many different colors, WP #115 'I in a Diamond' has only been found in the classic blue/green color.

This 3 1/2 inch float also has thousands of bubbles.

Found in Northern Japan.

This float has excellent provenance having come from the ex-Col. Rich Richardson collection.
