Eastman ISO Plus Nutritional Supplement

plus

This really has to do with Eastman in Rochester, but the key fob and key ring were found at a flea here, so let’s check it out.

The patent office shows that Eastman was granted a patent for this ISO Plus Nutritional Supplement, apparently for those of the bovine persuasion, in 1983, the first known date for the commercial use of this product.  As of 1992, however, the patent is shown as “Continued use not filed within grace period, un-revivable”.

Perhaps it just didn’t work out.
