All our grand prix posters start by acquiring an original poster, mostly the original race day poster, but sometimes have to settle for later edition prints or lithographs made from the original printing plates. Part of the fun of collecting these vintage posters is tracking them down, usually waiting for them to come up at auction, but it is slow going especially as we try to get the more interesting posters from the 30's, 50's and 60's, where prices are in the hundreds and thousands of pounds. The one thing we don't do is buy other people's reproductions - 99% are very poor quality, usually scanned from pages in a book, postcard or race programme. These are far too small to scan with any detail and become a blurry, pixelated mess when blown up to poster size.So we only scan originals at 300dpi with a £2000 Epson Professional Flatbed scanner - digital SLR cameras are getting better but a flatbed scanner still produces sharper results. For the typical sized original poster we end up with an 100mb TIFF image file.
