chain of late 1970's (-ish) FORMICA DECORATIVE LAMINATE color samples

JUST LOOK at all those beautiful and oh-so-trendy 'oranges' and 'earth-tones'?!! <LOL>

This brass chain holds 2" x 2-3/4" samples of the 30 colors/patterns apparently kept in stock at PEORIA KITCHEN TOPS, INC. -- though it is not actually dated I'm guessing the late 70's timeframe based both on the colors, and my own vague recollection that I retrieved the whole ring from a trashcan at the office where my Dad worked (a lumberyard, for which PKT Inc. was a supplier) back abouts then, when I'd sometimes go 'back to the office' with him after dinner -- while he worked late for a couple hours, I'd usually amuse myself by otherwise rooting around the place...? ;-) :-) :-)
