@magnut: any progress with that missing image, above?

Lorraine McKinney's first (known) appearance in TLI catalogues is 1973-Fall, see here, i.e. her red hair pics. can be approx. dated from then rather than, perhaps, mid-1975 mag. appearances?

edit: the first scan above of Marsha from Rascal, 1975-05: the settings there suggest photog. by John Kirk.
