Interesting early subdivision map of The Youngston on Wilshire Tract (Wilshire & La Brea, on the Miracle Mile).
The map shows sold lots, stamped in red, and notes that La Brea will be Business Permitted, and Detroit will be Duplexes.
An area a the bottom right (Country Club, Sycamore and Orange), is noted as "Grammar School". This is the current location of Wilshire Crest Elementary School.
The developer of this tract appears to be William F. Young, with the map drawn by Engineering Service Company.
