Found these three "Connoisseur " films limited catalogues the first two 69/70 and 75/76 show there offices as 167 Oxford street the 79/80 the bookings were obviously taken over by Harris Films Ltd.
The films advertised are mostly all foreign,a lot of French ones and the not so run of the mill English ones.
A strange one I picked at random is a French film Le Voyage en Ballon, (Stowaway in the Sky) which says copies are available in both scope running 60 mins and normal ratio 85 mins ??The film is about a balloon ride over Paris and French countryside.Won 7 international awards in its day.
Wonder what I'll find next?

I have one of the catalogues, mines printed on pale yellow and less than A5 too.
