Altemus and Company was mainly a printer in the 1880’s. In addition to blank books, stationery and the like, a number of Altemus printed stock certificates have been seen. Here is a second stock certificate (for this website) for a Colorado mining company. This 1881 certificate for 500 shares was issued by the Lincoln Mining Company of Leadville, Colorado. Note the “Altemus & Co. Phil” imprint on the bottom left.

It is impossible to know how many companies contracted with Altemus to print their stock certificates. Here is the fourth one that I have found.
