A mix of single pattern booklets and monthly @Knitters News, issued by the PASSAP Machine Knitting ( Originally Swiss, by the 1960s they were one of the main global knitting machine companies. These patters were intended for the Duomatic machines the company manufactured.
Some of these are unintentionally amusing to 21st century eyes ( particularly the poses adopted by the male models - pipe smoking 20 years olds in comfortable cardigans )
Includes full patterNs for all the clothing illustrated.
Some patterns have dates handwritten on the front covers.
