1976 Polaroid Pronto Centerfold Ad

This original ad came in a true centerfold and also as a 2-page ad that you have to align to fully display once outside the m agazine.  I'm offering both for sale.  Each will be @ 11 x17" fully opened.  The price is the same for both so please specify which you would prefer.  If you would like both I will reduce price by 20%.
