What I find interesting with this particular example is that, even with the level of restoration done, the corners of the card (portions that were wholly absent prior to restoration) were left slightly rounded. Maybe that was just an aesthetic choice too so that the restored card wouldn't look fake? I guess if you're rebuilding a card to that extent anyway, it really is up to the customer, but it's interesting to think about what motivates such choices and the people with enough money to be in a position to make such a choice. Not a decision I'll ever have to make, but it's fun to ponder
