In the 50th you didn't see one single Easter bunny in the shop windows. There were chocolate fishes symbolizing Good Friday and eggs. Unfortunately also little living yellow chickens, some of them survived but most of them died. Beginning 60th it was not allowed anymore and they were replaced by fluffy false chicken.
With the arriving of the EU (Commun Market at that time) the Easter Bunny arrived too and today you will see everywhere Easter Bunnies and eggs and only sometimes bells in chocolate.
