Most of the design and creative community has been obsessed with sign painting and hand lettering for a while now. It can more or less be attributed to the back to craft mentality and movement that seems to be inundating all forms of art.
I have not been spared, but on a personal level I find sign painting very nostalgic and it reminds me of my own childhood. For a few years when I was pretty young, no older than seven or eight, my dad made immaculate carved wood and hand painted signs as a way of subsidizing his woodworking business. I would often travel with him on the job and get to watch while he sketched, taped and finally painted a sign.
This specific sign painter Jacky Georges is obviously a skilled veteran and hold over from the generation before vinyl die-cuts and quick crappy window solutions. Work like this is a craft, it takes time to make, but because of that it lasts both physically and aesthetically.
