IPC juvenile group - who was who?

From the Comics 101 convention brochure we have the question...who's who on the elephant?

Conrad from 'Space Spinner' guesses Alan Grant with the big tie and John Wagner with the paste.

Barrie Tomlinson ID's John Sanders top right and maybe art editor Royman Browne climbing the ladder.

There may be some clues in this image taken from the Comics 103 brochure just 2 years later
