What is this mark on my original artwork?

In most cases, Gemma’s original artwork is created to be scanned and retouched for digital output in print or on screen. Therefore these pieces are truly unique in that some of them may carry errant marks or other irregularities. We consider this to be part of the ephemeral charm of these works and include them deliberately. If you wish to have a pristine piece of retouched artwork on your wall, these pieces may not be appropriate, otherwise please ensure you inspect the close up image of each piece before purchasing.
