I occasionally arrange one-off giclee art prints on textured watercolour paper. These are professionally printed, signed and double-mounted to fit a 40x50cm frame, as per the example opposite. I offer them for £80 plus £10 postage in the UK.
Send me an email from the contacts page if this interests you. Alternatively, if you're not bothered about a signature and it's purely for personal use, feel free to get in touch regarding a high-res image to print yourself.
