Here are my favorites:
This card I waited a long time for and finally got it in the spring of last year:
1934 Goudey Lou Gehrig #37.jpg
This one I also waited a long time for, I just sent it in to SGC:
1951 Bowman Whitey Ford.jpg
Finally, this one I happened upon at an Arlington show and thought it was a great card for the price (my only 19th century so far):
