A flower display in Bedfordshire

This is a picture of a flower urn in a public street. On the slide mount is written "River Walk Beds" which almost certainly refers to the location, but I couldn't find a River Walk in Bedford with an admittedly quick search. The car in the picture dates it to the early to mid 1950s I would guess, and the flowers go sometime in the Summer months.

This picture was mounted in a plastic two part slide mount which was filthy so I had to take it apart and clean it to get a scan.
