Dr Seuss characters were popular choices for children dressing up for world book day in Hackney.
Many school pupils in the area chose to go to school as The Cat in the Hat, Thing One and Two and The Grinch for the event.
Other popular choices were Willy Wonka, Where’s Wally and Winnie the Witch.
Characters to be seen at Queensbridge Primary School, in Haggerston, also included Dr Who, Jane Austin, Harry Potter, the Artful Dodger, and Meg and Mog.
Headteacher Sarah Bailey said: “This brings books to life, and it’s inspired the children.
“Their homework was to go away and make their own little book, it’s inspired them to think how to plan a story, the editing skills required and the illustration needed to bring the text alive.”
Horrid Henry was a popular choice of character for children at Northwold Primary School in Upper Clapton.
Headteacher Alison Kriel said: “It’s one of the best days in the school. The staff and the children were all really excited about the costumes they were wearing.
“Although we still have a lot of Disney, they are thinking about other book titles, and we even had the baddy from Lemony Snicket.”
Every door at the school was decorated to lead into a different story and children spent the following week touring the school to hear the different tales.
World Book Day is an annual event that is celebrated in schools across the UK. It was first launched by Tony Blair in 1998 in an aim to inspire a love of reading among children.
