Camille by Alexandre Dumas (ca.1921)
Altemus published this non-series book in two formats.
1. Boards with a dust jacket. 5.5" x 4.25". 75 cents
(The exact date of this format's first publication is unclear but the range is 1923-1925.)
2. Velvet calf, gilt top. Boxed. $2.00
(Approximate publication date is 1921)
I have not seen either of these two formats. This title was published in numerous Altemus publisher's series.
