For sale here is a unique set of US Documentary revenue 1898 'Battleship' and 'Commerce' stamps - mostly used - all in great condition though.

History:  In the continuation of providing funding for the Spanish–American War Congress authorized a tax on a wide range of goods and services including various alcohol and tobacco products, tea and other amusements and also on various legal and business transactions (such as Stock certificates, bills of lading, manifests, and marine insurance). To pay these tax duties revenue tax stamps were purchased and affixed to the taxable item or respective certificate.
