I have some old, classic computer games ranging from the 1980's to the late 1990's (eg. Shadow of the Beast, Starcraft, Total Annihilation, Awesome, etc.) with the original boxes. Some of these boxes have extremely cool graphic art printed on the front. I have the idea to decorate the walls of my home with enlarged versions of these works of art. I don't want to destroy the boxes in the process.
I Googled "how to copy games box art for wall picture" but there were no results. I'm at a loss for how to alter my query to be more effective.
What techniques might one use to copy and enlarge box art images to wall posters? Also - any legal or ethical issues with this? (I'm in the UK.)
