on a billboard
I was driving on Highway 35 on my way home from work. Up in front of me was a giant billboard advertising yet another jeweler, in ten-foot letters and bright silver watches like massive alien machines. The traffic slowed and stopped on the ramp as it bottlenecked further into the city, and my head turned to examine the sign and the blocked view of the cityscape and land beyond. Past it was another billboard, with the name of a casino as its only text, filled with collaged images of money, plush rooms, and dancers. A quarter mile further brought me to an advertisement for business management solutions. Another few hundred yards and I was urged to try the new sandwich at the new sandwich place. The sun set and the signs stayed bright as automatic light switched on.
The city grew dark and the hills beyond feebled out, existing only in our minds and finally not even there. All that remained were the well-lit and shiny reminders that lawyers were standing by to take my case to court, and that somebody's air conditioners would outlast somebody else's.
I had an idea.
I made the call the next day. It would put me back a good half grand, but it would be worth it. There would be no design meeting; I sent them the image and it was printed. A few weeks later it went up.
Now on my commute, when I paused in the crush of metal bodies, I looked up and saw mountains by Maxfield Parrish, reaching up to the clouds in impossible cragginess, rivulets and gushing streams painted down their sides, with the sun striking vibrant oranges and reds into the shadows of the rocks. There were trees in copper-patina green and still pools quieter than the middle of winter but warm as the first day of summer.
No doubt people thought it was the first part of a two-stage advertising gimmick, or a filler to be used when no one was renting space on the sign. But I was happy.
