Regarding the connection to Abe Lincoln, one plaque states:
"Grown from acorns gathered from tree under which Abraham Lincoln made a political address for Whig candidate William Henry Harrison in 1840 near Albion, IL."
At planting (from 1990 newspaper article) and current view (Feb. 2010):
The Theodore Klein tree museum marker at South Oldham County HS is very nearby, in fact just across the parking lot.
The school's arborical museum features a large variety of very healthy and impressive looking trees.
