I recently saw this book on Ebay. It features one of my favourite space toys, Colossus Rex, from the Colourforms Outer Space Men, a fact not lost on the seller as this is why it's being sold! The small pewter Rex figure shown by the seller for comparison, which is a good story in itself in the sellers description.
And whilst were talking Colossus Rex, we might as well look at the 1966 Eerie magazine cover, by Frank Frazetta, that probably inspired the toy's inventor, the great Mel Birnkrant, to design his rubber Rex.
Any more toys on books or mags out there?
