The location is Aberavon Beach and the photo was taken on a lovely Summer evening in late July 1969.
Day's amusement arcade is left, and you can just see the facade of Miami Beach Pleasure Park lurking between the two buses.
If you look closely at the bus stop flag in the left foreground, it will be seen that the sign has a 'Rhondda' legend cast onto it.
Yes, even Rhondda Transport's Leyland Tiger Cubs reached Aberavon via the spectacular Bwlch Mountain and Afan Valley, on a 'Summer Sundays Only' limited-stop service and often operating in convoy, such was the demand at this time!

Here's a Thomas Bros bus rounding the curve onto it's seafront stance on one of the intensive cross-town services.
The No.3 route linked the northern suburb of Goytre with the expansive Sandfields Estate via Port Talbot town centre and the beach.
OTX 137F was one of a trio of identical 36ft AEC Reliances with 51-seat Marshall bodies that arrived new in November 1967.
They were of the 6MU3R model, with AH505 engines and 5-speed all-synchromesh gearboxes.
With no power steering, they were heavy beasts to manoeuvre, though they were superb buses otherwise.
The destination blind displays "Sandfields Estate via Aberavon Beach, Four Winds and Dalton Road" and the livery is that superb 'Thomas Bros Blue' with a primrose waistband.
The fleetname font has changed from Gill Sans to a 'bold-extended' style.

Awaiting departure on the lengthy 7 route to Swansea is South Wales Transport Co 597, one of a sizeable batch of 30ft Park Royal-bodied AEC Regent Mk5s which were new in 1964.
