I don't know, I've found this picture in my collection, it is a Trading card from the series"The World famous San Diego Zoo-Animals of the wild", published in 1993. I have the complete collection, full of brilliant pictures of rare species !
But I think, the zoo kept rhinos always in the elephant mesa.
Actually it is quite an in-genius way of training somewhat difficult animals for being educational animals/animal ambassadors. They've been doing it for quite some time, just that they display them in this netted enclosure instead of not at all.
