Noticed this today. The certification number & photo on the PSA website don't match. The seller does appear to have the proper LOA for that number.

Something new, an old trick, or a legitimate PSA mistake (Looks like the next 80 or so PSA #s are the same item)?
I have thoughts on the authenticity of the autographs but I'll defer to public opinion & more experienced collectors.
