The colophon is a “term …used to designate the emblem or device of a publishing house” (Brown, 1994, p. 43). The colophon for the Charles Scribner’s Sons publishing company contains the initials C.S.S., a laurel wreath, the words Scribner’s Press, a magic lamp, and a book.
The book itself is 7.5 inches by 5.5 inches and just over 1 inch thick. These measurements include the cover. The pages appear to be folios, on sheet of paper folded in half and then gathered into quires and bound (Brown, 1994).
Here is a video which highlights the production of a quarto formatted book in the 1920s.
