IT takes some bare-faced cheek to take a dip in the icy North Sea without any swimming trunks.
But that is exactly what the mystery man in our main picture appears to be doing – just as another swimmer dives into the water.
Whitburn reader Fred Roberts provided the photo and said: “I think it was taken at the North Dock, it certainly looks like it. People used to swim there years ago – although most used to wear costumes!
“I was given the photo by a local historian and don’t really know much about it. It is certainly a different kind of picture to the usual historical ones of Sunderland though!”
Also pictured having fun in the sun is Greta Davies, who was enjoying a trip to Seaburn with her parents Alf and Mary Scrafton when the photo was snapped in the 1940s.
“It was taken during ‘shipyard fortnight’ just after the war,” she recalls. “You didn’t get real holidays away back then, as you didn’t have the money, but you did get a day out at Seaburn.
“It was always a special day. You’d bring a picnic and get your teapot scalded at a nearby shop. It was my job to get the teapot filled, and I’m holding it in this picture. The shop was just round the corner from Notarianni’s. It’s still there, and sells fish and chips now.”
