David:
That is what I thought also. But Stephen Ewen insists that we must have
the real name of author of that drawing. Both Stephen Ewen and I have
asked the Wikipedia author of that drawing (Wikipedia User:Quantock
Goblin) to give us his real name and he has politely declined. According
to Stephen Ewen that means we cannot use that image. I am too new to
Citizendium to understand why Stephen feels that way. If you could
persuade Stephen otherwise, at least in this one case, it would be much
appreciated.
Thanks for your response,
