1903 Pilot Acetylene Gas Generator

Vintage 1903 full-page magazine ad for acetylene, with a Cocroft ad on back. Item measures appr. 7" x 10" and is in VERY GOOD TO EXCELLENT CONDITION . Flaws include light edgewear, with staple holes and very minor creasing, and a small brown stain on the acetylene side, just above the bottom photo. (aaai) I do combine shipping on multiple orders. The shipping charge for each additional similarly shaped item would be .50 cents (U.S. only). Rates would be higher for larger, heavier items. ITEMS ARE RATED ON THE FOLLOWING GRADING SYSTEM: MINT (A+) - NEAR MINT (A to A-) - EXCELLENT (B+ to B) - VERY GOOD (B- to C+) - GOOD (C to C-) - FAIR (D+ to D) - POOR (D- to F)
