Beautiful Vintage A. E. Luff & Son (of Nottingham) Paper Ribbon, which would have been used to tie together bundles of books.
The ribbon is printed with:
'The Hill Bookshop & Library, 87 High Street, Wimbledon Common, SW19, Tel: WIM 0198'
At a guess, there is approximately 50+metres left on the reel.
The width of the ribbin is 5mm.
