Tony:
Like you, I'm a FNG here too, and we are pretty similar!  I'm also 34 and have a five year old son, Ewan, who is just starting to show an interest in collecting baseball cards.  I like the old stuff, he likes Chase Utley, his favorite player!
Right now I am focusing on the T205 set, but I pick up any old tobacco card I can.  There are a few cards that I have all ways wanted.  I have a few so far (T206 Mathewson with black cap [I like the looks better than the white cap PERSONALLY], a T206 red background Ty Cobb, and a T206 Lajoie.)
Forgive this next thing, but my son is next to me and wants me to post this smile face for no reason 

.
It's nice to meet a fellow collector around my age who I can share our passion with!  God bless us; we are in for a journey!
