Great image!! It doesn't get much cooler than that for a baseball scene.
To scan these negatives (3.0" x 4.25"):

I bought an Epson 4990. You can get them used for $100-$150 on Ebay if you are patient. There are newer models (Epson v700 and v800 I think) that can also scan larger negatives, but they are considerably more expensive. Most scanners won't work. You might find a local photo expert (run of the mill places won't have the right equipment), but this will probably cost about the same as buying an Epson 4990.
