I have been searching around for old images of the zoo, to get inspired for some tasks, and I have come across an absolute treasure!
Someone has got the original zoo guide book and scanned in all the pages and posted them onto a flickr account here.
As a form of research, and just pure productivity, I have taken these scans and have re created the guide book. I laid out the scans onto indesign. Cropped and adjusted where needed, and printed out as a booklet.
Below are some work in progress screenshots.
I now have a complete original book, that I can use as reference or make into a product.
