Apologies for the poor quality of the images but the torn-out page arrived, folded many times, with one of these cameras - and it is a bit faded after 57 years! Paint Shop Pro has helped to clean them up but that's as good as I can get it.
Photax, the UK distributor for Yashica and Contax (and Super Paragon lenses) was very active in advertising the marques in the late 1970s and early 1980s. What's unusual is the inclusion of Contax and Zeiss gear - clearly trying to demonstrate that the FX-D is a genuine contender for the more serious, and presumably well-heeled, photographer. Sales for both the Yashica FX-D and Contax 139 were pretty buoyant in the UK during that period.
