File copies from H/K's Industrial Designer.
There is an autumn 1975 folder that includes a lengthily 4 page explanation to the dealers on the company and products.
There are two sales bulletin sets from 1975 accompanied by their preliminary product announcement specification sheets. There is one each for the HK 2000 cassette deck and the 730 receiver.
Finally there is the stiff bi-fold cover Manufacturer/Dealer Franchise Agreement. It is unused and unsigned.
