A wonderful 2 page pamphlet advertising the 10 books of the Children of the Bible Series has been discovered within a Series #137 book (One Syllable Series). This advertisement, as shown below, lists the titles and includes some pictures that are found in several of the books. It is unclear as to the exact date of this piece. The half vellum books were published for a number of years beginning in 1905. The catalogue lists 25 cents as the book price until the teens although the books themselves list 25 cents as well as 50 cents during this era.

I would guess 1905-1912 date.

Advertisements like this probably exist for most Altemus series of the early 1900s and teens. They are exceedingly scarce.
