TWO VINTAGE POSTCARDS: HOOVER DAM AND BONNEVILLE DAM

Description

The records show that Hoover Dam is located near Boulder City, Nevada.  It's actually on the border between Nevada and Arizona.  This postcard looks like it was the cover to a souvenir packet about the dam--probably from the 1960s.  It appears to be a real photo postcard with a few words added to the bottom left corner, as well as the "Greetings" line added to the top.  You can see a lot of detail in the photo, but it is not crystal clear quality.  There is an average amount or less of yellowing to both sides of the postcard.
Bonneville Dam is located 45 miles east of Portland, Oregon.  This postcard appears to be from the 1970s.  It's a little heavier cardstock and was not part of a packet.  The back of this postcard describes it as a Curteichcolor 3-D Natural Color Reproduction.  It has about the same degree of yellowing as the other postcard.
They both measure 3.5" x 5.5".
