This is a L.E. Smith Crackle "By Cracky" green wine glass. It is authentic Depression Glass. Smith produced By Cracky or Crackle in the 1920s-30s. McKee produced a nearly identical Crackle pattern in the 1920s. The patterns mix well together and can be nearly impossible to tell apart. I believe this wine glass was made by L.E. Smith. It is 4 5/8" tall and 3 1/2" wide. It is in excellent condition with no chips or cracks.
