Today’s menu is dated April, 1971, the last month Union Pacific operated the City of Los Angeles, which was discontinued when Amtrak took over on May 1. Other than the date, the menu is identical to those posted the last three days.
The cover shows the ruins of Mission San Juan Capistrano, which was founded in 1776 but destroyed by an earthquake in 1812. As shown in the Google satellite photo below, the area of the photo is largely unchanged today except that the ivy covering the ruins has been heavily trimmed back. The statue in the cover photo is of Father Junípero Serra, who founded this and eight other California missions.
