Seneca Cameras, Seneca Camera Mfg. Co., (Rochester, NY), Catalog K, undated but 1911, ~5"x8", 76pp

This catalog is identified on page 76 as Catalog K ("Destroy Previous Issues"), but does not bear a date or copyright.  However, the previous catalog, Catalog J, had a 1910 copyright, and the succeeding catalog, Catalog L, has a 1912 copyright.  Therefore, despite being undated, it is clear that this catalog can be assigned a definite date of 1911.
