Spitfire Juice Glasses

5 ounce (?) juice glasses, likely made by Dominion Glass in Canada (marked with a capital D).

My parents were antique glass dealers for many, many years.  They gave me these glasses years ago since I was interested in aircraft and aviation.  These are 4 1/2" tall and have a Spitfire enameled onto them.  There are three total; all in perfect condition.  Buy one or all.

I'd like to pass them on to other aviation fans.  They will be well-packed and shipped safely.
