Leni â Thanks for your comments.
After I spoke to you, Leni, I was shown a much later "J Lloyd" signature at the Cambridge fair. Apparently in later life he hotted up his signature by making it a little blobby, not as extreme as that of Jak
the Evening Standard cartoonist, but heading that way. Unfortunately I've yet to discover when his signature went arty, but it was certainly post-war.
It is worth noting here that apparently in later years he was happy to add his signature to his unsigned earlier work, so his signature on a piece could be much later than the decoration.
