Years ago, when the children were young we had lots of Ladybird Books . They were always around at jumble sales and cheap to buy. Mostly they were in the series of 'Well Loved Tales' or 'Children's Classics' We also had some of the 'People at Work' set, some of the bible stories and some on various subjects I found to use with my Cub Scout Pack.
Going back to many many years before and I remember being bought the Ladybird book of Queen Elizabeth I to help me with finding out about her for a primary school project. I had no idea who she was, I'd chosen to be in the group writing about her because I thought she was the present Queens mother.!(In my defence I was only 8 at the time.). We also had a few others - mainly the baby stories including some of the early ones like - Bunnikins Picnic Party.
About 15 years ago we were on holiday somewhere and I came across the set of "What to Look For" for the four seasons dating from the 1960's. The illustrations in these are famously by Charles Tunnicliffe, a well known Natural History Artist.
I discovered they've been reprinted and modernised and the covers are below but I've no idea what they have inside now.
I thought I'd look out for some of the old Ladybirds that we didn't have and found this in a charity shop for 49p, some of the rarer, older Ladybirds are expensive second-hand online.
There is one form of Ladybird books that I really don't like - that's the recent "humourous" Ladybird books for Grown-ups......tacky. I think they are given as jokey Christmas presents - and are often in charity shops, so perhaps other people also don't like them much.
I found a list of all the original Ladybird books HERE
