English: From https://vcc.copyright.gov/. Documents copyright registration of "Advanced Fourth Mousie Reader" and "Introductory Mousie Reader." It contains two numbers: "9605" and "31132." The check mark has been seen on other cards, but I do not know what it is. The image is in the public domain. Vcc.copyright.gov says "A virtual catalog card image is an exact replica of the physical card from the Card Catalog." This work was created between 1870 and 1897. It is card number 0061, whatever that means.
