Anyone recognise what’s going on here in Great Yarmouth?

Harleston man Ian Denney came across some old black and white negatives from the 1950s, and they’re a bit of a mystery.

“I found some pictures I had taken near the old power station. It appears to be some kind of motorcycle speed event, probably your readers would know the answers.

Can anyone help Ian, and do readers recognise any of the people in the pictures? Email Letters at anne.edwards@archant.co.uk
