YOU can insulate YOUR home!! This painted steel sign probably dates from the 1950's. Measuring roughly 20"x32" or so, I got it from what was then the Simpson-Powelson Lumber Co. in Galesburg IL when I worked there in the early 1980's. I don't remember handling/selling Schundler Mica Pellets by that time (lots of pink fiberglass insulation bundles, though) if they were even still being made, the product might have been determined to be "hazardous" by then...? My absolute favorite part about this sign has always been its depiction of the 'lady of the house' in her dress and high heels, standing on a plank dumping a bagful of "easy to handle" mica pellets into her rafters...? <lol>
