Not exactly sure when the Tappan Flying Circus operated but was probably late '20s or early '30s...this 11" x 17" poster was one of a small stack found in garage of one of the performers after he 'went west' years ago...that was Sid Cleveland who did the "Blindfolded Flight'...perhaps the event at Boone Airport was cancelled because of weather and the posters were not needed...sounds like it was a real thriller flying circus act...think Tappan operated out of Phoenix, AZ...the posters are still in good shape with only a little fading on some....happy to combine shipping if you need more than one
