Update: This has now been solved. Thanks.

I am researching a commercial artist named 'Carr' who founded a design studio in Auckland, New Zealand in the 1940s.

His earlier work includes covers for comic 'Laughs' magazine:

He specialised in glamour pin ups and cereal card albums. Clients for the studio included Mosgiel Woolens, Bell tea, and 'Peter the Pilot' for Timaru Milling, who seemed to be a mainstay client.

The earliest record I've found for his work, or the work of 'Carr Advertising Studios' is 1944 and the latest around 1955, after which time he seems to disappear. He signed all his work quite obviously with a distinctive signature (see image).

I have trawled through thousands of records from 1944-1958 and found little, which is odd. Although Carr was a common name with thousands of references - which isn't helpful - I've also explored the possibility that 'Carr' was shortened from a longer name like 'Carroll', 'Carruthers', etc. Still no luck.
The best possibility so far and a tentative one, is a certain Roy Carr who was ascribed profession draughtsman and resided at 340 Mt Eden Rd, in 1958. I'm hoping someone will run across this and know something.
