Blah Blah Cafe, the Jean-Michel Jarre forum

[(Unknown)]

Hi all !

I was wonderding why the A in Jean and the M in Michel where special.

For instance on the Oxygene cover :



I've seen those on other stuffs :

A book by Jean Marie Périer (french photograph)



And the movie poster of Mean Streets



Do you know what's the symbolic behind that ? Do you know other examples ?

I believe it's maybe related to the "Franc-Maçons" as spotted here (in french)
