These booklets were stapled into the center of the Summer 1960 issue of the Bolex Reporter (Vol. 10, No. 3). Judging by the numbers I've seen, it appears they were often removed, however. A large range of 8mm cameras, lenses and accessories are listed; a price list is included on the back, for all items shown. A table of specifications for Kern and SOM Berthiot lenses is also provided.
