Vintage 1970s Set of 2 NO FLAME Fire Illustrated Pinback Buttons Antique Rare

These were acquired at a “Home Show” in Dallas in 1979 or 1980. I could image they were used as advertising for some type of domestic fire safety product. They’re cool antique pins, and are a great novelty for a collector. Both are mildly dented & discolored. Each measures roughly 1 2/3” in diameter. Sold as pictured.
