South Yorkshire Transport Museum is holding its latest event on Sunday.
The museum, on Waddington Way, Aldwarke, is open from 10am to 4.30pm and will have heritage bus rides, a large display area and the chance to see one of only two Rotherham motorbuses ever restored.
Entry is £3.50 for adults, £2 for concessions and £8 for a family. People bringing a pre-1973 classic vehicle get in free.
A vintage bus will provide a shuttle service from Rotherham Interchange.
