I had the brilliant idea that Fisher-Price should re-release all their toys from the 70's and 80's. Anyway, it appears they might have had the same idea!
I can't find it on their official site, but I found this cute milk truck on Amazon. If you go to this page you can see down the bottom "others also bought" some of their other stuff, like record player and TV. So cool! I think it's called the "Basic Fun" range, I shall investigate further...
(It's just occurred to me Gus won't know what a TV, record player, telephone or milk truck is... oh that makes me feel old!)
