1960's breakfast cereal pack models

Does anyone in the UK remember these? In particular (around 1965) a series of dogs' heads; I remember a spaniel and a dalmatian. Also around the late '60s a series of WW2 aircraft. Of these, the one I really remember was a fabulous "Lysander"... I think about that model to this day!

The cereal was probably Kellogs Cornflakes.
