MISSION MIRROR, San Francisco, Dec. 13, 1879  Printed in the masthead is: "The only Paper Wholly Printed and Published at the Mission, a Locality Containing 20,000 Inhabitants."  This would be the famous Mission Delores, still located on 16th St. (see photos & the hyperlink).
Page 2 has a political notice supporting: "For president in 1880, Ulysses S. Grant, of Illinois".
Four pages, some margin wear with minimal text loss (see lower left corner in photo), should be handled with care.
