Product advertisements in Altemus books are basically unheard of. Leinbach & Bro advertised its clothing store but that was in books that Leinbach gave away.

See: http://henryaltemus.com/ephemera/leinbach.htm. Here is the only example that I know of a product advertisement in an Altemus book. It is bound into the extremely rare 1895 Altemus edition of Baby’s Requirements by Elisabeth Robinson Scovil. The book which is 6.25 x 4.5 has a limp leatherette binding.

As you can see, here is an ad for Ivory Soap. It is placed in the back of the book and there are no other ads present. I cannot explain why this ad is in this book.

There is a chapter on bathing infants in the book but it does not mention Ivory Soap.
