They\'re only paper prints Alan, so if you\'re gonna laminate them, I\'d also mount them on something like hardboard aswell; that\'s what I did.
The 1st lot were secured using plastic cable ties, but after they went the journet after only a day or so, I put up some more, this time securing them onto the gate / railings with TESPA bands (steel bands you often see holding the doors of lamp posts on....errmmm, I used to work in the Street Lighting Section....lol). They lasted a wee bit longer, but if somebody\'s intent on removing them, they\'ll get them off even if they\'re welded on, unfortunately.
Good luck with them, anyway - I hope they have the desired effect.
