The model catalogues form a great reference source.
I have managed to collect a large number of the Matchbox, Corgi and Dinky catalogues.

The very early ones were available free from every toy store. As a kid I think I got a new catalogue every couple of weeks.

The pages contain the front cover image of some of the catalogues that I have. Some of the pages are large and I have split them into groups to keep the size down a bit. WARNING - each page contains approx 9 x 60K images and may take a while to load.
