I wrote to the Rutland, VT historian for info on the company, but of course, being the weekend, I don't expect an answer right away.
The one with the choirboys is $22 and I looked for other ones. Religious themes seemed to be popular when these items were manufactured, I saw some depicting the Last Supper - probably premiums form funeral homes. Mine would probably be of more interest to someone from Rutland, about 75 miles from me.
