Just a great set of c. 1950s brass alphabet stencils, which interlock to allow for even spacing between letters, making them great for sign making, etc.  With a nice weight, they are also great to as objects and signs in and of themselves, and will stand up when locked together, as pictured. The brass on these has a particularly nice patina, and they come in their original box, which is in great shape. The complete set includes a couple of spaces as well as commas, apostrophes, and a period. 

The stencils measure 4" tall; letters are just taller than 2". Box measures 4 3/4" X 3 1/2" X 1 1/8".
