I photographed the Mars Rover Spirit examples in Virginia and Oregon.
I first saw the one at the Evergreen Museum in 2015. When I returned a few years later the rover on display is clearly a simplified version of the one that was there earlier.

Three years later and the museum had clearly swapped out a detailed example (above) for this simplified replica.
