Small gifts for small sponsors?

Is there anything we can give to our small sponsors ($25-$100) like the grocery store and the bagel people right off the bat? Like one of our buttons? Or a photograph of the team that they can stick to the wall? Perhaps we can take one of the kickoff photos and print it out in color with 'Proud sponsor of the Castilleja Robotics Team' on the top of it. That's a really easy token if immediate appreciation that we could give them for less than a buck each.
