The description on the back of the card states:
DESERT LANDSCAPE
Colorful jagged mountains, arid wastelands, and the grotesque desert Joshua tree form a typical scene on the desert, now crossed in comfort on smooth, paved highways which connect one cool green oasis to another.
–The description refers to the US Highways, and later Interstate Highways, which facilitated safe travel across these otherwise uninhabited and inhospitable areas. Even today there are large uninhabited desert regions, many of which are state and national parks.
This card likely dates from the 1950s.
