I don't think Building # 1 with Chicken Boy atop is in the 1920's snapshot. 5558 N. Figueroa has a build date of 1937.
Here's the block in 1931 with the empty lot where 5558 would go.

Building # 1 is to the left of Chicken Boy and comprises 5560-62-64 N. Figueroa. It was built in 1924.

Building # 3 (Lee Real Estate) had gone by the time of the 1931 aerial - moved to Eagle Rock Blvd. in 1928.

Can't find what happened to it but building # 2 (Van De Kamp's) also looks to be gone by then.
By 1931 they had an outlet not far along the street at 5819 Pasadena Ave. My best guess from the aerial.

One Mack Sennett reference book suggests 5819 Pasadena Ave. could possibly be the Van De Kamp's that appears in a 1927 comedy
Smith's Candy Shop.
It first shows up at the twelve minute mark.
