Hand-painted FLO-PAQUE salesman sample card
If I am not mistaken, Flo-paque used to be a brand of Floquil, which if I am not mistaken again, was purchased by Testor's...the folks who help your kid paint his models. This salesman sample card not only shows "the actual colors" it was hand-painted! I assume the card was passed along a line and dabbed by each "color specialist" who specialized in...oh, let's say "maroon" before it went on to another expert. Pretty cool. Of course, after "copper" it would be set aside, likely overnight, before the reverse "lime" artist would start the back.
