Care bears was fun when I was young. There are bears in Bananas n Pyjamas as well. Benjamin Bear in the Secret World of Benjamin Bear is quite popular too. I like them all, cuzz they are cuddly and cute.
Defiantly, Winnie the Pooh. We also had the 'comic' hard cover books of Rupert the Bear. My father bought the books from overseas for his bookshop in the Sydney (NSW) CBD. (Can anyone, my old age, remember what the name of the shop was?)
