The Internet holds a lot more anaglyphs and stereograms from the Pathfinder mission in 1999. You should be able to find some with a simple search. Here are some anaglyphs of Pathfinder's Sojourner rover that I built from stereo pairs that I downloaded from the JPL's photojournal site. The first one is small enough to work as a stereo pair; use the leftmost two images for cross-eyed viewing, the 2nd & 3rd for parallel-eyed viewing.
