Just another piece of evidence to refute the claims that you can’t find anything good on eBay.
This is an 1872 sight draft from Hamilton, Ontario to Boston, Mass., with a pair of Canada #FB51 and 2 singles of FB46 (Van Dam numbers) along with a single U.S. #R135.
Documents with both U.S. and non-U.S. revenue stamps affixed are quite scarce, especially from the 1st-3rd issue era. Examples from the Spanish-American War era (1898-1901) are a bit more findable, but still very uncommon.
Even with the condition of the document itself being a bit frayed around the edges, this is easily a $150-250 item at retail.
