Vintage #912C Chip and Dip Set

This NIB chip and dip set has an 11" diameter chrome plated fluted shell and crystal dip bowl "for elegant serving of chips and dip or shrimp and sauce." The shell is still in the plastic wrap and the glass bowl is still in the cardboard holder. The box is in good condition with some wear and darkening from age. I would guess that the set is from the 70's or 80's. Shipping and ins. will be to price based on zip code. Thanks for looking at Simply Silver!
