I have recently found some pictures of Royal vacuum cleaner ad clippings from various magazines of the '60s-'90s on eBay.
One of these is dated 1986. Their claim is "Royal ... The Last Vacuum You'll Ever Buy." Shown across two squares arranged diagonally, is a model 880 with the 1977 style bag but also with the front decal first seen on 1982 and later models of the model 501 hand vacuum. As I take it, the decal from the 501 was probably first used on the Royal uprights around October 1986.
