Many thanks to reader Gerry for sending me a copy of this. I've ordered the CD compilation this is on, but it seems to be missing in transit [Update 2016: I am pretty sure this has been 'temporarily' out of stock since I wrote this post]. By the way, that sleeve was for the Japanese release of the French version of 'Un Prince Charmant' - so unfortunately there's no Japanese version of 'Baby Pop'.
A four-page magazine spread from a 1969 issue of French magazine Mademoiselle Age Tendre. French-speaking readers: does this say she had her own make-up line? *faints*
