January: Chris Porsz took a series of photos in Peterborough. This is at Queensgate before the shopping centre was opened in 1982.
February: Chris says he rarely takes photos of buildings without people near them. He said: "I find buildings drab, people bring them alive."
March: A road sweeper, known as Taffy, gets his hat blown off by the March winds on Bridge Street. Chris tried to capture the character of the city.
April: Chris is a paramedic in Cambridgeshire but takes photos in his spare time. The rain gets heavy on Long Causeway.
May: Chris would like to recreate the photos. He knows who the policeman in this photo is, but would like to contact the boy, who would be in his 40s now.
June: Apparently Vimto used to come in stripy cans. It is believed that, unfortunately, the Afghan hound is no longer with us.
July: Annie Gertrude Blunt and Jim Shahid Shah show some neighbourly spirit outside 134 Gladstone Street. Jim sadly died in 2009.
August: On the Town Bridge. Chris is interested in seeing how the city and people have changed in 30 years, which is why he wants to recreate the photos.
September: The calendar is being sold all around the city and captures memories before the landscape changed dramatically.
October: It is early autumn and Alf Newton is pushed in his wheelchair by his nephew Jack with Marjorie Coles on Long Causeway.
November: The kissing couple. Tony and Sally got in touch with BBC Cambridgeshire after hearing about their photo, which was taken at Peterborough station.
December: If you spot yourself in any of the photos, let us know by emailing email@example.com and we will put you in touch with Chris.
