Here we have LB's signature photo
And here a photo of Jim's car from his detailing thread

Notice the front wheels are angled in both photos, the spokes are in the same position relative to the car, car position relative to faded white lines is the same, identical color and texture of the parking lot surface, and the same crack in the parking lot surface under the rear half of the vehicle
On to the next photo

This time we have a shot looking at the front of the car. Again we see the angled front tires and shadows from the wheels and bumper match LB's signature photo. In the sig we see a lighter green tree behind the seats. In this front-on shot a very similar tree is behind the driver side mirror. As for the vegetation, in both shots is nicely cut grass, followed by overgrown rough, and then dense trees.
One last thing. The signature photo file name is DSC_0034 and Jim's detail photos are DSC_0028 - DSC_0045. It's in the range.
Frankly I don't care who LB is but overwhelming evidence indicates that either he is MNBoxster or he "borrowed" the signature photo.
