It's not from a UK catalogue, I have just checked mine.
It does look like pages 10 and 11 from a standard A4 catalogue, and looking at the sets featured around 1993/94.
if you look closlely bottom left you can just see what looks like the tops of the numbers 1 & 0.
Page 11 (if it is 11) might have had images of the individual sets shown down the side of the image which have probably been cropped off, that would make the centre line appear off centre.
Hope you get an answer from the website soon.
