I sure haven't.
I just found this and I don't recall EVER seeing it before. This is a scan of a 3" x 3" print.
This is the Holy Trinity School Bus on September 17, 1953: I just turned 6, so this must have been at the beginning of first grade for me in the old HTS building where the parking lot is now.........and Mom - of course - got a shot of me exiting the bus after school.
To me, this is like finding the old Aerosmith van on American Pickers.
