1949 Bowman Paige- same year as the iconic 1949 Leaf, and looks even better

T206 Cobb red- more common than green, but looks just as good

1951 Bowman Mantle- has quietly risen over the years. I remember getting a PSA 1 for like 700 5 or 6 Years ago

W514 Joe Jackson- probably one of the cheapest cards you can get of him honestly, but its rarity and the fact that it was from 1919 (100th anniversary coming up) are key

Exhibits do seem to be drawing a lot of attention! Early vintage postcards in general are becoming more mainstream. Such an interesting side of the hobby with many rare and yet to be discovered examples out there.
