This is for 2 brochures for Endless Caverns, 1 Natural Bridge Hotel and 1 Shenandoah Caverns.  The Shenandoah one is dated 1929, the Natural Bridge Hotel one is dated 1930, I could not find a date on the Endless Caverns brochures.  They have wear.  The Shenandoah one  has a tear to the back cover.  The Endless Caverns brochure at the bottom of the photo has wear to the bottom of the back cover and a tear up the spine on the cover.  Please see photos.
