When I was a kid the zoo in Edmonton was known as the Storyland Valley Zoo. It was a product of a different era and in addition to the expected animals there was a make believe aspect to the place with lots of artificial life forms from story books etc - 'three men in a tub' comes to mind; a likeness of the butcher, the baker and candlestick maker carefully balanced in a small tub that was permanently anchored in a pond. And the little train that ran around the place - unforgettable but not really very zoo-like by today's standard.
The 'Storyland' aspect disappeared long ago and the Valley Zoo has undergone a transformation that continues. The makers of some of the newer elements commissioned a series of photos recently - this is one of my favourites.
