This is an original AdvertisementMASTER that all the magazine ads and brochures were made from! This one is from 1978. It is very rare and unique part of Bob Carver History! I bought these from the actual photographer who worked with Bob Carver and the Phase Linear Crew in the late seventies. I can give you his email to verify if you like...This oneis about8" by 10".This is very collectable and will certainly go up in value over the years...I have MANY other Phase Linear Items on my eCRATER Store, please check them out.
