This coaster, which is more or less just a hard piece of smushed cardboard, but beautifully printed with the right ink, is the first in a series to commemorate the A16 logos over the years. The embroidered patch was primarily sewn onto packs from the mid 60's until around 1972. When A16 we introduced other innovative products in the late 60's like dome tents and sleeping bags, it went on those too because that's what we had in the box. Later those pieces of gear earned their own specialty embroidered logo patch.
