Here's some nice close-ups from the Library of Congress aerial photo of the San Jose railroad yards in the summer of 1906. I suspect the photographer convinced some of the local businesses to paint their names on the roof so they'd be visible in the photos.
The H.L. Losse packing house at 392 San Pedro St. is a name I hadn't already seen.
Another fun detail: Those look like Santa Fe boxcars in front of J.B. Inderriedden! The three story Rosenberg packing house also is another example of how packing houses aren't always low to the ground and temporary.
