It was October 1970, and these boys and girls were just some of a group of 400 schoolchildren from Newcastle West End who were enjoying a day out at the zoo.
But 50 years later, look for the place today and you'll find little trace of it.
The zoo operated midway between Stanley and Annfield Plain in the ground of Harperley Hall.
The attraction in North West County Durham drew families and school trips in the late 1960s and early 1970s.
An advert in the Evening Chronicle announced the zoo's opening on Tuesday, June 21, 1966.
It would be open seven days a week from 10am 'until dusk'. Adults could get in for 2s 6d (about 13p in today's money) and children for 1s 6d (about 8p).
Stanley, a former colliery town, perhaps wouldn’t seem the most likely location for a zoo, but indeed it was home to an exciting array of wildlife five decades ago.
The zoo was owned by a colourful character called Martin Lacey who would perform with a dancing bear and who would go on to be a presenter of children’s TV animal programmes.
Years later, in the early 2000s, one former employee fondly recalled working there.
Lynne Aitchison told the Chronicle: “At Stanley Zoo I had a wristwatch which a barbary ape took a liking to. A hand came out and grabbed it and the blooming thing ate it.
“There were two pumas, Dallas and Amber - and we had a leopard called Toby, a cheetah called Bobby, and some cute little lynx.
“But my all-time favourite was Marcus the lion. He was gorgeous. He was also the first big cat I ever went into a cage with.
"And there was Bobby the cheetah who used to eat the brooms and chew your wellies!
“They all had their individual personalities and I loved looking after them.”
It was initially hoped Stanley Zoo would pull in at least 150,000 customers a year, but this proved to be an over-optimistic figure, and for a while the place was taken over by Flamingo Park Zoo (today it's Flamingo Land) in North Yorkshire and re-branded as Pelican Park.
The children in our photographs appeared in a Chronicle story in late October 1970, and we told how 400 boys and girls, aged four to 11, from Elswick in Newcastle West End were bussed to the zoo and back free of charge (and complete with travel sickness tablets) by the big-hearted drivers of Northern General Transport.
Sadly the zoo never became the major attraction it was hoped it would become.
In December 1971, the Chronicle reported how it would close by the following Easter. The curator told our reporter how "mid-week trade was almost non-existent" and "there are only one or two people at weekends"
By then, the troubled zoo only had 50 animals and 100 birds left on display and these would be transferred elsewhere.
Stanley Zoo's five-year existence was over.
