Some of the same area was included in a 1902 Charles Pierce aerial taken from a balloon, which may have been released from at or near Chutes Park. I've enlarged and split the panoramic photo into
thirds (with some overlap), but here's the link to the whole thing at the Huntington Digital Library:

1. The left third, looking west. The intersection with the jog at lower left, above the signed "Pierce," is Figueroa and 23rd; the intersection above the lower right, where there's a westbound streetcar,
is Figueroa and Washington. East-West streets between 23rd and Washington, left to right, are 22nd St (stops at Fig), 21st St. (jogs at Fig), and 20th St. (stops at Fig). West of Figueroa,
between 23rd and Washington, the next five north-south streets are Lovelace, Estrella, Bonsallo, Park Grove, and Norwood (there's a large school building on the NW corner of Norwood and 21st).
South of Washington, Estrella turns into Chester Place (

On the southwest corner of Figueroa and 23rd is the home of Mrs. Michael Connell, shown here after 1910:

On the east side of Figueroa, in the middle of the block between Washington and 20th Street, is the home of Mrs. E. Gardwin at 1924 S. Figueroa. It looks like there might be a garden on the lot
to its south. I like the chimney support in this c. 1900 photo:

2. The middle third, looking northwest. The intersection above the lower left corner of the photo is 18th and Figueroa -- there's a big jog -- where Patriotic Hall is today. The two north-south streets
that run off the bottom of the photo are Hope (left) and Grand (right). At the bottom center of the photo, we see the tip of St. Vincent's, north of Washington on Grand.
The prominent white building with domed roof just above 18th and Figueroa is the 1st Church of Christ, Scientist, at 635 W. 17th Street, seen here c. 1904:

On the west side of Figueroa, the third house north of 17th Street (on the SW corner of Figueroa and 16th) was owned at one time by Joseph Maier. This is a c. 1890 photo:

The area between Grand and Hope -- with Pico on the South -- that looks like a baseball field is Fiesta Park:

South of Fiesta Park on Hope, just north of 15th Street, is California Hospital, shown c. 1900-05:

3. The right third, looking north. In the lower right corner, with its roof conveniently painted for future researchers, is Palace Stables at 1801 S. Main. The intersection of Hill Street and 18th Street
is at the center of the photo at the very bottom. The next three streets north of 18th are 17th, 16th, and 15th. Today, the Santa Monica Freeway runs here between 17th and 18th Streets:
One block east and six blocks north of 18th and Main, with the shiny roof, is St. Joseph's Catholic Church (1901-83) at the SE corner of Los Angeles St. and E. 12th St. Here it is c. 1901-15:

And between 16th and 17th, on the west side of Hill Street, we have the 16th Street School and Fire Station 10 (1920s photo with Metropolitan High School to the west):
