Set of Instructional guides published by Hasselblad in the 70s.  Very good technical information and photographic examples.  Booklets are each 10-25 pages in very good, unread condition with just a little wear to covers.  Please see photos for titles and condition.

I am new to selling on Ebay, but have been selling books online for 20 years with many happy customers.  I try to be as accurate as possible with descriptions and photos, but please ask any questions you have regarding condition before bidding on items.
