I don't see what the joke would be? Aside from the fact that this is Pre-War board, and I'm bringing up J.Rob's name? But then again the '71 Blyleven was mentioned.

Unless you can point me to a lower price on the card (that didn't happen more than 2 years ago), I don't see the joke, particularly as the card is part of the master set, and there is only 1 PSA 9 that trumps this card. VCP average on it is $1,050, so I'd say $806 isn't a bad deal at all. Maybe not a "steal", but certainly not an inflated price by any means.
