On many of the designs I have shown, the background is plain black becasue it shows up both the black & white and color designs best. On the poster, however, I wanted to use a more interesting background; so I created this one with a pattern made of interlaced bicycle frames. Other variations on this are possible.
There is an online site that turns digital images like this into interior murals. Perhaps, you might want that for a wall in your shop. It could be put on sheet rock panels to make it portable. In that case, I could expand the design to include more rings and more complexity as needed. The design I have created is intended to look best as a poster, but as you can see; it is adaptable to smaller sizes.
