David A. Smith goes through the technology and painstaking craft behind his artwork for John Mayer's 'Born & Raised' album

Look at that insane level of detail! Traditional sign work like this is wondrous because, as John Mayer expresses early in the video, it’s something most people have seen but don’t know a ton about; including its origins or what the style is even called. What’s stunning about David’s work is how passionate he is for passing on his work, teaching it to others, not letting it die out. It’s a shame when you see how beautiful the finished products are to realize that so few people do work like this nowadays, and how plentiful it once was.
