Found Collection

I'm looking for 4 British stamps issued in 1979, all of childrens' books:
Peter Rabbit, Winnie-the-Pooh, The Wind in the Willows, and
Alice's Adventures in Wonderland.  I also may be interested in
the postcards of the same; I've never seen them so don't know for sure.
I would like them in unused, mint condition.  If you can help,
please e-mail me.  Thanks.
