"What you have is an excellent example of a 1950s Aladdin Angler Thermos, manufactured by Aladdin Industries, Inc. of Nashville, Tennessee. Aladdin made a lot of Thermoses and lunch boxes over the years, but is probably best known for their picture lunch boxes like the Hopalong Cassidy and Space Cadet models that bring big prices at auction. This neat thermos utilized their "Sweet Seal" stopper and was offered in two sizes (pint and quart) by itself and as part of a "workman's lunch kit." They are still surprisingly usable even today. In nice condition, the Aladdin Angler is worth $15-$25 and slightly more if found in the original box. To see such an example, as well as a couple of Aladdin ads from the 1950s, click here."
