Just curious if anyone else had the same concern about this card.....

just from my opinion - no card in hand - but I think it's just an optical illusion only seen in the scan taken of the front. That corner seems to be fine when looked at from the back.
That said - the card doctors are well practiced with sophisticated tools available with which to ply their trade - and people lining up to buy their wares. Getting something altered past a TPG isn't all that tough - especially with multiple submissions going through the black hole of grading - and then they're in.
As an aside - I have returned maybe 2/3 cards over 20 years and had to accept a single return - as it turns out from the esteemed leader of this site - long before he would go on to be king :-)
Well it was around 1994 and I bought a T207 from someone who is now a friend and sometimes national table partner - early base ball collector and dealer Glenn Mechanick. I was 2 years into collecting cards and as I started to educate myself by buying books and listening to dealers. As a result I was now afraid of all the things I was reading and hearing about fakes and alterations - I saw monsters around every corner. I think it was Parsipany(?) - a table with "the old stuff" caught my eye. A quick negotiation with the guy standing smiling behind the table and the card was mine. I was excited to bring my T207 home (my first of it's type) as I was just starting an N/T type card collection of base ball cards. I sat down at my desk, put it under a table lamp and pulled out a magnifier. Oh no! There was significant crazing to the photographic surface and my mind went immediately into panic mode. I figured the surface had cracked as a result of someone cutting the card along the edge and causing something like a shattering. Argh. I've been taken! In a panic I drove back to the show (from Brooklyn) THAT DAY. I warily approached the table as I had no idea how returning the card would go. Glenn stood by quietly listening to me drone on as to my observations and suppositions (I really didn't know very much - still don't - likely it was obvious) and he took the card back without a problem - in fact he thanked me for calling it to his attention.
A few years later we started up a conversation at a show and moved onto a friendship. One of the good things about our hobby. Next time I see him I have to remember to ask if he was just placating me.
Likely there was nothing wrong with the card......
