Perhaps someday more info will come to light to show the very earliest use of this mark!

During the earlier years, many of their bottles carried an “I. CO.” mark, and later an “I G CO inside a diamond” logo. This Diamond/I mark was used by Illinois Glass from 1915 up to 1929, and is seen on many antique and vintage glass bottles.

ABM (Automatic bottle machine) production was begun at Illinois Glass in 1910, and although it seems more likely (to me) the “I in a diamond” trademark would have been first used around that time, the U. Patent & Trademark Office data indicates Illinois Glass Company actually claimed use of this particular trademark was begun in 1915.
