Adding all three adds a certain personal touch and can increase interest in your art via a scarcity factor. Some artists always do this as they’re proud of their work. Others feel sheepish if they’re not yet a big name. It’s your art so you portray it as you like, whether that be with a title, edition number and your name, or a combination of all three. The edition number generally goes on the left (1/25), the title in the middle and your name/signature on the right.Some photographers think editioning can be a bit odd, especially if you only ever sell three of a ‘1 of 50’ edition with the other 47 never actually existing.
