The other images are doubles. We use them to fold over our advert boards but if you cut carefully between the two images you can make 2 logos each 85 x 20 mm.
These cost £5.45 for 10 doubles (20 actual images when you have cut them in two.). They are also self-adhesive and come as in the picture.
Here is a picture of some of them in use on some of our Plain Black Tyre Covers around a bend.
