So, after the Belgian publicity, here’s the Belgian movie poster, with text in both Dutch and French. The image is the Cummins painting from the British poster… although the signature is gone, there’s an overall reddish tint to it, and there are lots of tiny differences that certainly make it look that it’s not a poor reproduction but a complete re-painting of the image. The logo is the American marquee-lights style logo, not the hand-scrawled UK one. The space at the top, I’m guessing, is for the theater to print their name and maybe the showtimes.

The text:

EXCELSIOR
FILMS

TIMES
SQUARE

Na “Saturday Night Fever”
“Grease” “Tommy” en
“Jesus Christ Superstar” nog
een denderende muzikale
film van Robert Stigwood.
Een film die davert op de
hartslag van de hedendaagse
jeugd.

Après “Saturday Night Fever”
“Grease” “Tommy” et
“Jesus Christ Superstar”
un autre film éclatant
de Robert Stigwood.
Un film qui tremble sur la
pulsation des jeunes
d’aujourd’hui.

My attempt at a translation of the blurb from both languages:

After “Saturday Night Fever”
“Grease” “Tommy” and
“Jesus Christ Superstar”
comes another brilliant musical film
by Robert Stigwood.
A film that shakes to the
heartbeat of the youth
of today.

If anyone wants to contribute a better translation, please do.
