The first Playhouse in the Park Magic Show poster: Ken Klosterman circa 1970’s?

The first poster from Playhouse in the Park Magic Show,  This show was to continue for decades.  It was the brainchild of Ken Klosterman. It was sponsored by the Cincinnati Academy of Magic and Allied Sciences (CAMAS) of which I was a proud member.. This is a very nice looking poster and has ben stored for over 50 years. it is near mint.  The size is21.5 x16 inches.. I am guessing at the year but i think I am close. Tickets were $1 and $2!
