This document is probably the very first Ovation price list ever printed with acoustics, electrics and amps.
You can notice some very interesting sthings like the Folk Classic model which was available in 4 colors. According Bob in which we can trust, only 4 prototypes have been produced:
a black, a red, a green and a blue one.
Another interesting thing, an Electric bass named "Williwaw" which was the first name
of the "Typhoon II" (thanks Dave for the info!!).
