Oddity by Morrison and Grist from twenty years ago. A Romance subject, "Romeo 4 Juliet'. Was it just the one page?

Just in time for Christmas, a piece of Grant Morrison ephemera unseen since its original publication. 'Juliet 4 Romeo', with art by Jack Staff's Paul Grist, first appeared in Letterbox, a spiral bound book given away as a prize to schoolchildren in a letter writing competition circa 1990.
