The Good Humor, Hallmark and Barbasol branded razors were in all likeliness made by the company Conrad in 1932-1936, they have tapered bakelite handles and are open comb razors in two piece design. Apparently Prybrands (Conrad) made these razors for other companies to market in their stores, and this thus information of the actual makers and their history is quite hard to find.
The razor is in great condition, and is definitely worth owning if you want something unique very few others have. It is also quite light for folks who love razors of this nature.
It is very light @ 26 grams, upright it stands 84 mm tall.
a Great find indeed!
