I know that it is something of a shot in the dark but we have one or two rather learned collectors among us, so here goes: Could anyone identify the initials "JF" on comic postcards, published by Brook Publishing Company Ltd. London W.1 ?

I suspect that will be tough one - often less is known about the cards of that era than about Edwardian ones.

Is this the chappie in question?
