This graphic comes from the 1923 American Type Founders Catalog, which I own. I modified it by cleaning up the scan and making it transparent.

Musical-themed printers ornament, from the American Type Founders Catalog, 1923. Cleaned up and made transparent by author.
The American Type Founders Catalog was more book than what we would think of as a ‘catalog’. It was hardbound and nearly 1000 pages long. The company – which was, in turn, a congolmeration of smaller companies, made letterpress type and equipment. Their catalog was both a catalog and a demonstration of letterpress – it was completely typeset and bound using the type and equipment they sold. It contained numerous faux ads and announcements to demonstrate the versatility and quality of the type they sold. It also attempted to discourage using newer forms of printing such as Monotype.
Despite their best efforts, the company went out of business in 1933. There is an interesting website about the history of printing at Columbia University, which houses the Typographic Library and Museum of the American Type Founders Company. Originally the website of an Rare Book exhibit from 2001, one of the pages is specifically about the American Type Founders Co.
