You gotta love teh interweb. As many will know, the photos on this blog are hosted on Flickr. I like the ability to upload a photo and then blog straight from the site.
I also watch a few people's uploads and occasionally spot things that deserve a wider audience. Today finestoneminiatures uploaded a couple of very nice sheets of garage signs taken from his own photos. To use them, all you'd need to do is print onto some semi-gloss photo quality paper and cut out with a sharp knife.
Result: Instant decoration for the price of a bit of ink and some paper. Even if they fade a bit over time the results shouldn't be unlike the real things fading in sunlight !
Boat modellers might like to print them on some of that "make your own decals" stuff and then use on racing boats for sponsorship logos. Give them a coat of varnish and you'll be fine.
Sheet two here.
