Leaflet - for Kindle novels

I've just seen a flyer from a local author who's doing his own marketing for a new novel. The A5 grey and black leaflet is something of a contrast between the high-tech Kindle platform (where he's selling the novel) and the low-tech marketing wheeze of shoving leaflets through the letter-box in the area. Personally, I wish him well and hope that it leads to a spike in sales. It's also a polite way of advertising as the e-book format means that he can't advertise in local bookshops. Well, I doubt any will advertise a rival platform for him and it doesn't seem to be available in traditional page-turning format, only in touch screen format. I suspect we're in that interesting 'in between' stage where technology and tradition are finding ways to work together, even if it does seem a bit odd.
