This has been used for a while now as a separate map from the weird 2019 map, why they didn't use this as the official map is a mystery to me.
This was the "Monkey seeker map", which included pictures of all the monkeys the zoo held and where on the map they were, but it wasn't the official map
@Mr Gharial And, weirdly, when I was there last month on the dispenser box for these is a sign saying "these are not maps", in some kind of extreme existential desperation.
Couldn't work out if it was meant to imply 'leave these for the kids as a bit of fun' or 'don't worry that there's no food or toilets on this one - they are there!' but either way this clearly is a map.
