WMEX question

[Donna Halper]

I just found an old undated photo of some folks at WMEX, one of whom looks 
like the late Mac Richmond.  The only clue as to the photo's year is a 
slogan on the wall-- "WMEX:  Home of Modern Radio."  I don't recall that as 
a slogan from Mac's era-- they used Color Radio a lot and several other 
slogans whenever they changed to new permutations of top 40.  But does 
"modern radio" ring any bells, or did I find a picture from right when Mac 
and his brothers bought the station in 1957?
