This picture sleeve features a nice color photo of the prototype 1963
bound sidejack Mosrite Ventures Model (held by Nokie). Note that the
vibromute bridge is just a sanded down guild bridge without the Mosrite
logo that would appear on later vibromute bridges. Also note that the
neck pick-up is not aligned with the slant cut at the base of the neck.
Don is also holding an early sidejack model but the body does not
appear to be bound.
