Dating Los Angeles Zoo map

[SoCalChevy]

I recently got this old LA Zoo map. I believe it is from the late '70s or the early '80s, but any help dating it more correctly or precisely would be appreciated. I'm having difficulty uploading photos to this thread, so I will upload them to a gallery and provide links here:

THEY HAD MARBLED CAT! Aaaaahhhh! I lived near Los Angeles Zoo and starting photographing it as an adult around 1989-90. It must have been some time before this because I think I would have remembered marbled cat (which I have never seen and is top on my list of unseen cats). However the physical layout of the zoo looks as I remember. I forgot to look - is China Pavillion on the map? If not it was pre 1984, if it is then it was 1984 or later.

Another look shows China Pavillion is not there. I have no idea the exact date. But they also list cheetah and I do remember a cheetah on one of the hillside exhibits when I visited as a child in early or mid 1970's. So it could be anytime early 70's to very early 80's. Sorry I cannot be more specific.
