correspondence courses

[steverod]

I am trying to get some information about two correspondence courses which used to run, one between the wars and the other I think in the 70's.  Macdonald Smith worked from Bloomsbury in London and taught privately as well as by post and E J Pickles ran the Cowling Inst. from 60, New Oxford st. which offered a correspondence course with 37 illustrated cards.  I would be grateful if anybody has any information about these.

Many thanks,

Steve
