Here and there I have added some specific info related to that particular item.
I will not go into detail on the production, manufacturers, etc of Christmas lights. There are specialised books, publications and websites available, already well known by serious collectors:

- Book, with over 1300 detailed pictures of Christmas light bulbs, by Robert T. Iwamasa:
“Antique Christmas Figural Light Bulbs”, ISBN 0-9652858-0-4; a MUST for the serious collector
website : http://www.antiquechristmaslightbulbs.com/index.html

- Book, very thorough information on production, manufacturers, etc. by Robert T. Iwamasa and Patrick Fay:

A peep in the book via google books.
