new pages at paddington

for those new to funkypancake you may not know that i collect numbered posters. this started when i noticed that each poster in paddington train station had a page number on it.
i’ve never seen the book that these giant pages (about A0 size i think) come from, but we have seen a number 57 before, but it looked slightly different. Probably a different book.

and this one is page number 5 which is quite intriguing. must be a new book.
