Do you think it could be part of that nursery across the street on the southeast corner of 11th & Flower?
In all honesty, I doubt it.
(surely the illustrator would have included rows of trees if it were part of the nursery) -
and would have labeled it as part of the nursery instead of leaving it blank.
I guess the best clue is the word ORD that appears on the 1921 baist map.
