How'd you make the stencil Bud? My dad was an old time sign writer who would free-hand signs like that with a brush, but he did "silk screening" of metal signs for the local real estate agent. I remember helping him do a batch of a couple hundred signs back in 1980, I've never worked so hard in my life!
You could certainly make some good dough doing signs with those skills, but they wouldn't be of any interest to "American Pickers" etc, as they're not old, original "Patina" signs. Good job. 
I used AutoCAD to design the signs using a sign painters font. I have to tile print it and tape the sheets of paper together. I used some spray adhesive to glue another layer of paper to the back because a single layer of paper was too flimsy. Then I cut out the characters with an exacto knife, being careful with the A, D, B, O, P’s leaving the centers intact and stencil like. It’s tedious, but when I’m in the moment I just have to tell myself to get it done.
Then I used the same spray adhesive on the back of the stencil and stick it to the board. I spray the black drop shadow with a can of spray paint, then pull up the stencil and move it over a little bit, then spray the white and the other colors. I have to brush touch the A, D, B, O, P’s etc.
Once all the colors are done and it’s dry enough I bugger it up with sandpaper and scotch bright pads.
Funny thing...I’m actually watching American Pickers at the moment and they’re buying newish hand-painted “tribute” signs from a dude who made them himself.
