Ohio Caverns Postcards

 Both of these great old unused postcards showing Ohio Caverns have identical backs.  The back of each says-

Largest and most beautiful of all Ohio Caves.  Its exquisite crystal-white stalactite and stalagmite formations are nowhere to be found in greater profusion or artistic settings.  Thousands visiting Ohio Caverns acclaim it "The Most Colorful Cave in the Country."  It is a veritable subterranean para
dise, spectacular beyond description.  Located on State Route 275, near West Liberty, Ohio.
