2 1/4" tall and 2 7/8" across the base. On the base of the pedestal is embossed ARMSTRONG'S WHITALL TATUM COMMUNICATION INSULATORS. The CD 155 style on a glass pedestal was produced by Armstrong as a salesman's sample or a give-away. The glass is clear and the condition is excellent. This is certainly one of the outstanding salesman samples and is rarely offered for sale. Last one on ICON was 3 years ago. I'm offering this little beauty at low book value of $350 and I'll pay the shipping to anywhere in the U. S. or Canada.
