Rovex returned to Harrogate in 1970, and will have been showing some of the Pippin-produced Spacex toys if only as a preview. At the time there was a competing international toy fair in Brighton, also in January of each year, where I've seen evidence that Rovex did have some later toys on show (see Newsreels page - use your browser's Back button to return here).
