The ad was featured in the June 1948 Crockery and Glass Journal, on page 53.
The ad features Westonian 'Veri-Thin" line with the Anthony cut. Borchert was a decorating company located in Weston, VA. They used glass manufactured by other Weston area companies; Westonian was apparently a blanket name for some of the cut glass lines they produced. Borchert also established the Colonial Glass Company, which manufactured their own glass and later did their own cutting.
Thanks to Tom Felt for the additional information on this company.
