As an example from a stack, two examples taken from 1978. One with new prices and below an overview of the used instruments. The frames that were made on a typewriter were often printed on pastel colored paper (pink, green, yellow, etc.) and sent by post. How about a new Telecaster for converted 440 Euro (FL 965, -) or a used Fender Jazzmaster in white from 1963 for converted approx. 450 Euro (FL 995)?
The first list is from May 1978 and shows the catalog and discount prices. The second overview shows the prices of some used cars and is from November 1978.
When I bought my new black Stratocaster in 1978, it became one with a "rosewood" fingerboard. Saved 85 guilders compared to the "maple" version.
Although I have more such "stencils", these are just examples.
