Private Die Perfume Revenue Stamps- Missing From Many Collections.
The Tax Act of 1862 provided that companies being taxed under the proprietary schedules could propose stamp designs and submit them to the government, and when approved, pay to have the die made for producing them. In return, the company could advertise on them and buy them at a discount from the general issue ones. These stamps were often ornate and beautifully designed. They would make a great addition to your collection.
