Postcards 
Trumptonalia.
A set of 31 1960's kids tv postcards by Arthur Dixon - of which 18 were for Camberwick and Trumpton.

These were all produced by Arthur Dixon in 1969.
Clearly a set,although I've yet to find any evidence that they were collectively marketed as such.

Numbers 1 to 8       feature stills from The Herbs ( shown on tvherbs.com )

Numbers 9 to 26     feature stills from both Camberwick and Trumpton ( 9 for each series )

Numbers 27 to 31   feature stills of Basil Brush

The titles of the 18 Camberwick & Trumpton examples,below,are reproduced exactly as written on the backs.
As are the reference numbers.And each one is listed in reference number order.

Most,if not all,of the images were specially staged shots,as opposed to being lifted directly from the original footage.
Some were also used for other products -most notably,the jigsaws.
