For a few months in the summer and fall of 1909 the Attleboro Stamp Company used an affixing machine to separate and affix stamps to its news letters ("The Attleboro Philatelist") and price lists. Although created by a stamp company the purpose was commercially inspired and used. Most of the known correspondence are on wrappers for the "Attleboro Philatelist", those on envelopes are quite scarce, this and one other sold in 1988 from Larry Cohen's collection are the only examples that we have seen with a dated flag machine cancel .
