I had an opportunity to chat via email with the last surviving son of the founder of Alberts Display and Novelty Company. He told me that his father, Philip Alberts, shut down the firm's operations in 1948. Their Halloween output was restricted to a period from ~1941-1946. Therefore, the dates attributed in the book to all items made by the Alberts Display and Novelty Company are slightly off. The correct date range would be ~1941-1946. Please see pages 29 and 58 where collectively three items made by the firm can be found.
The above verbiage was taken directly from my errata page. Please print a copy of this errata page and keep it with your book to ensure the information available to you while you shop or peruse is as up-to-date as can be.
