This is called
A Two Face Mask
Sometimes I wonder what to do with old designs and stuff I play with on the sketchpad. I wonder if I can ever monetize this stuff and a few Ideas came to mind. One is recording the process with OBS and making videos of art in progress, but for old art that is difficult.
I put a lot of my old pictures on RedBubble and a few on TeeSprings. RedBubble is very easy to use. TeeSpring gets bogged down if I make a lot of products at one time. Every site is a little different. Zazzle is the most human of all the sites and seems like something you work at slowly.
Anyway, here is the progress I made with the Two-face mask on Zazzle. When I asked to sell it there they said it was pending for some review. It is also interesting the profit for the designer on Zazzle is limited at 10% while RedBubble and TeaSpring really don't give any limit to mark ups.
That said the prices at Zazzle still seem a little high. Maybe that's why they are doing the 50% off sale. I will look into Zazzle from time to time but don't think it is the easiest to work with or the best chance at sales.
