VERY FINE APPEARANCE. THIS IS THE ONLY RECORDED BLOCK OF ANY BRINKERHOFF STAMP, AND AS SUCH IS A WONDERFUL EXHIBITION ITEM.
The Brinkerhoff machine was designed to perforate only strips of stamps, and so this block had to be folded between stamps in order to fit into the machine.

VERY FINE. THIS IS THE ONLY RECORDED USE OF THE 5-CENT BRINKERHOFF TYPE I ON A COVER, AND PROBABLY FIVE OR FEWER COVERS EXIST WITH THE 2-CENT ALASKA-YUKON WITH BRINKERHOFF TYPE IIA PERFORATION. A PHENOMENAL USAGE.
Mixed usages with the Brinkerhoff and U.S. Automatic Vending Machine Co. are rare. (Image)
