Leinbach and Co., a Reading, Pennsylvania clothier, used Henry Altemus books as advertising vehicles as early as 1893 and as late as 1915. On the cover (front or back) “Compliments of Leinbach & Bro” was stamped in gold gilt. Then in the front and the back of the book a one page glossy ad for Leinbach was bound in.

A number of examples are shown at http://henryaltemus.com/ephemera/leinbach.htm.

Here is an 1894 book that has the typical gold stamping on the front cover and the bound in glossy advertising pages. In this instance there has been no change in the ads since 1893.
