Question on Authenticity

[sb1]

I am handling an estate for an ex MLB press corp member and have come across several signed 8x10's. I am quite certain of where and when the photos were taken, however not sure if they were signed there or at a later signing. No certs as all of the material he seems to have was obtained in person, however I am aware there is always a chance with an older collection he may have gotten some bad material via other avenues.

I'll start with these three before posting others so as not to clog up the works.

Thoughts??

Those all appear authentic to me

Thanks, as most will see these guys were all players in the 1987 All-Star game.

Here are a couple of more, but I am not sure of where these would have been taken. Although Rose and Carter appear to be in front of the same batting cage as above.
