The following pictures are taken, for want of the originals, from various sources, mostly books or magazines; often the illustrations were similar to the original but differed slightly in some respects. Possibly it was to simplify for reproduction purposes or simply for speed for a sketch to order as in the pictures found in Childrens books, such as the Oxford annuals.

This one of Jans must date from 1939-on, its a barrage ballon moored in Hyde Park almost opposite the Albert Hall. The bowling green is still in the same place.Now in New Zealand, and found in 2015 in Portobello Market, a few hunderd yards from where the Gordons lived. Needless to say I am jealous! Thanks to the new owners for pemisssion to use.
