Help identifying what catalogue this page is from..?

[CheeseWedges]

Hi Eurobricks :)
I bought a bulk lot of a bunch of catalogues and instructions that arrived 2 days ago, and I've identified what almost everything belongs to, even though most of it was ripped apart into single pages and parts of pages. I have this part of a page which I've found out is for a "golden stud" advertising campaign TLG did in 1974. So I checked scans of 1974 catalogues, and the back page showed the same illustration of the three golden bricks, but on a blue background. My page has a yellow background, and completely different content on the back.
 

 

I've looked at 1974 catalogues on Bricklink, Brickset, Peeron, Worldbricks, Internet Archive and lego2000.nl, and haven't found my one. I think mine is a special version since it has part prices on the back. I think that means it's a dealer or service catalogue? (I don't really know the terminology for catalogues but have seen them on Bricklink). Other snippets of catalogues I got had a code that I could type into Bricklink (eg: 112085 OS-IB), but this snippet doesn't have that fine print on the side like the others. It's probably European though since I live in New Zealand.

So, anyone have any ideas?
Thanks in advance!

Its' certainly British, looking at the money used in the prices, and the address to send back to. (British LEGO Ltd.)

Maybe mid 70s to early 80s? I really don't know. Sorry I can't be of more help @CheeseWedges!

Oh, right, I forgot that it's obviously British because of the pence! So it's a British 1974 catalogue, but not the standard one... 🤔
