In Jatujak market, I've seen several of these stalls selling books to make models. You pop out the cardboard parts and assemble them into model windmills, towns, boats.
I decided to try one myself, so I bought a model of Tower Bridge London, the famous London bridge that raises to let tall ships pass under it. See the photo below of my finished bridge below.
The book cost 30 baht, it took me about 40 minutes to assemble and it looks good. I was a little disappointed that some of the card had damage on it, the printing was torn off in places. So check the one you buy carefully to see the printing is OK.
But I'm really pleased with the result, ignore the two extra pieces, they are, erm, spares :-)
A map to where I saw these last on sale is below, see the green arrow.
