Boutell & Maynard
Boutell and Maynard were a cost-conscious match manufacturing firm in Minnesota. They bought a die that was being abandoned by Winslow's Green Corn when the tax on canned vegetables was repealed in 1867 and had it altered, rather than pay for having an original one designed. The result is the firm's name on a tin can.
The Boutell and Maynard stamps were issued from September, 1873 through August of 1875. 2,140,000 were issued on silk paper.
