info on older bulls

I'm looking for some information on some older bulls.  Not looking to buy semen, but have genetics that run to them.  Boss has embryos to be put in by some of these bulls and I'm just wanting to see what I'm in for.  I would like to see some pictures of the bulls.  I've done some internet searching, but haven't had time for much and I haven't gotten much for info yet.

Looks like angus bulls I don't much about them.

Yes, they are all angus bulls.  I have pedigree's on them, I'd just like to know a little more about them.
