covers from the USA

On 24th March I got not only a postcard but also three covers from the USA. 

On the first cover is a postmark about the McKinley Exhibition Station in Canton, Ohio. Sure really sure, but this probably refers to the William McKinley Presidential Library and Museum. McKinley, who is definitely not one of the famous presidents, began his career as lawyer in Canton. Two of four Jack O'Lantern stamps (issued 29-09-2016) were used on the cover. 

Inside was this card of the Petroglyph National Monument in New Mexico. Created in 1990, this national monument protects a variety of cultural and natural resources including five volcanic cones, hundreds of archeological sites and an estimated 24,000 images carved by Ancestral Pueblo peoples and early Spanish settlers.

On the second are a second McKinley postmark and the other two Jack O'Lantern stamps. A nice set!

The card in this cover shows the Old Geronimo Mission in Taos Pueblo, which is on the UNESCO World Heritage List. The first Franciscan mission arrived in Taos Pueblo in 1598, but the contacts between the local inhabitants and the priests were not very friendly for a long time.

Two more Vintage Circus Posters (issued 05-05-2014) were used on the third cover and a postmark about the Year of the Ox, but neither town nor date can be read.

The card in the last cover shows the Pueblo Bonito, the largest and best-known great house in Chaco Culture National Historical Park, which is since 1987 on the UNESCO World Heritage List.

Thank You very much Sam-Quito!
