QR Code Tattoo And Looking Off

Is there such a thing as a QR Code tattoo? I'm betting there is. This is obviously an envelope drawing. I had done this early in the day before I got some very sad disheartening news. An artist friend of mine passed away this May and on my birthday. I hadn't seen him since pretty late 2019 at an art show reception. And I was going to email him to schedule a visit. Kept saying it to myself. He and I go back to the early 90's. Anyway, I feel selfish now. Measuring 3.5 by 9 inches, this is a simple gel pen drawing or two. And Original Jones Art is telling himself once again that time waits for no man in northwest Austin, Texas or anywhere else.
