My own sense of style says that the frame's metalwork and paint should define the look, and that look should be an understated elegance. I have no desire (or need) to plaster my advertising on your bike.
All creative works, bicycle frames included, deserve to be signed by the artist. To that end, my frames carry a single, small copy of my builder's "signature" on the top tube. In the full-frame photos on this site, you'll have to look hard to spot this small graphic.
My frames are painted by Keith Anderson, whom I consider to be a valued partner in this enterprise. Keith places his own artist's signature in an out of the way location on the left chainstay.
From the beginning, I have adhered to this understated styling, not worrying if it might turn off potential customers. Recently, to my delight, I am being contacted by customers specifically because of this styling. They've never met me, and likely don't know anybody who owns one of my frames, but they've been searching for a builder who will hold off on the decals. Through the power of the internet, they've found one!
