I've been lazy the last couple of days, so I thought I'd make up for it by posting the two alternate posters for Massimo Dallamano's Cosa avete fatto a Solange?. Made in 1972, Solange is the first film in the loosely held together "schoolgirls-in-peril" trilogy that was written by Dallamano. A firm favourite of mine, this is an excellent giallo set in London featuring a great cast and a beautiful soundtrack by Ennio Morricone. Dallamano went on to direct La Polizia chiede aiuto (What Have They Done to Your Daughters?) in 1974, but unfortunately he passed away in a car accident in 1976 before he could conclude the triolgy, so the last film Engima Rosso (Rings of Fear) was directed by Alberto Negrin.
There's no signature on the locandina posted above, but the one below is made by the great Sandro Simeoni aka Symeoni.
