5" by 4 1/2" w 2" H. Silver plate lid stamped International Silver Company. Cigarette Holder or fancy trinket dish? I used it to hold my business cards on my desk when I work for a bank many many years ago.
I am not sure what its initial intended use was for...but, I am sure it has a great Art Deco style, look to it. The glass is thick (old time feel) with those great round balled curvy feet. The silver plate lid is curvy and has a geo like design. Nifty.
