This is an image of two large government buildings on the campus of the Oklahoma state government center in Oklahoma City.

The description states:
SEQUOIA AND WILL ROGERS BUILDINGS
Oklahoma City, Oklahoma
There modernistic buildings, housing State and Federal offices, are part of the Capitol complex. They are named in honor of Sequoyah, famous Cherokee Indian chief who invented the Cherokee alphabet, and Will Rogers, Oklahoma’s favorite son and world-famous humorist. “The Avenue of Trees,” a part of the landscaping, is made up of 77 trees; each tree represents one of Oklahoma’s 77 counties.
–The autos visible in the image indicate that this card dates from the 1960s.

This image shows an unusual subject, a simple but radical curve in a highway in Oklahoma. Because of the greater than 180 degree turn in the road, these features are pretty much universally described as horseshoe curves.

The description states:
HORSESHOE CURVE
This beautiful curve is located on highway 77 in the Arbuckle Mountains near the beautiful Turner Falls recreational area. Also close by is Price Falls.
–The description places this road feature in south central Oklahoma. Turner Falls are not particularly imposing at only 77 feet, but are tied for the highest waterfall in Oklahoma.
This postcard likely dates from the 1960s.

This image shows the Frankoma pottery pattern called “Wagon Wheels”, which is self-explanatory.

The description states:
WAGON WHEELS — Eulogizing the pioneers of the Great Southwest. Many other pieces have cattle brands, horse shoes, etc., as decoration, available in complete table service. Made in Prairie Green, and Desert Gold. Write for free catalog of Frankoma. Visitors always welcome at Factory Display Rooms, open weekdays 8 a.m. to 8 p.m.
FRACKOMA POTTERY — Sapulpa, Oklahoma
–The color scheme shown here is obviously Prairie Green. This pattern seems to be more popular than the Westward, and now comes in a larger range of colors.
This image likely dates from the 1960s.

Shown in this image are many of the standard pieces that make up the “Westward” pattern of dinnerware sold at that time by Frankoma Pottery. The pattern refers to the form of the pottery, not the coloring used.

The description states:
WESTWIND — Clean, sweeping lines form this lovely serviceable pattern. Made in Woodland Moss, Peach Glow, and Prairie Green. Write for free catalog of Frankoma. Visitors always welcome at Factory Display Rooms, open weekdays 8 a.m. to 8 p.m.
FRANKOMA POTTERY — SAPULPA, OKLAHOMA
–This is an example of the Woodland Moss color scheme. These designs are now widely traded through online selling sites and can be purchased in pieces or collections.
This card likely dates from the 1960s.

This image shows the main building housing the Frankoma Pottery, a business known for it’s locally dug clay products and particularly their dinnerware designs.

The description states:
This is the Home of Frankoma Pottery, designers and manufacturers of Art Pottery, Sculpture, Dinnerware and Ceramic Tile. Write for free catalog.
FRANKOMA POTTERY — Sapulpa, Oklahoma
–The business was established in 1933, and moved to the current location in 1938. This image is clearly from the 1960s as indicated by the parked cars.
