Proper maintenance record keeping (circa 1952)

Hi All;
Recently went to remove the original rims and tires from my 1938 Hudson.
After popping off the first couple hubcaps I got to the left front.
What did I find ?   A perfect condition piece of oil paper with the date 9-26-1952 as the most recent time the front bearings were greased!
Proper records kept in a suitable location , where the next competent person is sure to find them!
hmmm 3-29-2021 might be time to grease them again...

Wonder if next you'll find a note saying when it was painted last?
