Circular Periodic Chart of The Elements

Chris R. Hagness writes:

"I own a wall chart that doesn't seem to be in your database of periodic tables. It's a circular 'periodic chart of the elements' published by Dickinson Brothers, Inc. in USA, distributed by American Seating, copyrighted 1961 by H. Edmund Matthews, Jr.

"I have never been able to find any information on this on the internet. Not on Edmund Matthews, no old catalogs from American Seating, no reference to this particular circular periodic table. I've never seen another of these anywhere, and I've been looking on and off for 10 years. I can't imagine this would have been a popular selling item. If you have any info, that would be appreciated!"
