Postcards From the Edge: Mom's Family Cards 47

This post features three vintage postcards.  This first one, an aerial view of Kanas City, Missouri, is from 1934. 

There's the First National Bank of Kiefer, Oklahoma.  That looks like a secure institution.  Is that an oil well in the background?  This one is from 1908.  

"A little fun with the feed boss."  This postcard is from 1912 showing an Army camp.  Note that all of these cards have a 1-cent stamp on them.
