A bloggerly conversation prompted a check of my basic Ladybird facts, but alas, many of the sites feature crawling gifs that are a little too animated today.
This site has a curious gallery of icons that in an un-clickable state read like poetry.
And some good articles: The original Jane - from Ladybird's Peter & Jane books
The Adventures of Wonk is one of the most sought-after series of books by Ladybird collectors.
Craig's Ladybird Book site is well done. My favourite series is 563 Learning to Read but perhaps The Party was so dazzling to me as a child it may have set the party bar impossibly high.
