Henry Altemus Company

A phonograph album published by Altemus has been discovered.

The album pictured below has 12 numbered pages each with a slot for a record. It is not dated and there are no clues as to the publication date.

On the back of the cover the Henry Altemus Co. name above the word Philadelphia is noted.

I assume it was published sometime in the 1920's but this is a guess.
