First Issue Revenue Perforated Collection. Complete less Nos. R21c, R31c, R99c and R102c, all appear unused except Nos. R14c, R39c and R49c, mounted on Scott Specialty pages with a couple of shades included, while we cannot guarantee all are unused, this seems to be the case judging from the strength of the colors of the stamps in the collection, there also may be a few flaws here and there, still overall Fine-Very Fine, it would be quite a challenge to duplicate this handsome lot, Scott Retail as "used"
