Alabama Caverns was once a tourist attraction"18 miles east of Birmingham. Curt Teich published card postmarked 1932. The picture appeared in the July 17, 1927 Birmingham News. It does seem an interesting photo for news publication in 1927.
The Crystal Caverns Park chrome card, circa 1955, appears to be the same caverns, advertised in Clay, Alabama and established in 1927. Card printed by Alabama Postcard Company
