The reason I ask, is because in 1992, BG sent me some educational documents along with this catalog which, according to the details... It appears to be much older without even a mention of an email address.

...and inside the front cover is a picture of a 100.000.


...and this is the inside of the last page along with the inside of the back cover.

Could there have been two colors of the 100.000 plaque..?
