Here's what I've found in the various Detroit Directories:
1901 - First listings appear for "Avenue Theatre" at 80 Woodward and the occupants of the "Avenue Theatre Block"; includes a listing under "Cafe" for "Thomas Swan" at 87 Woodward
1904 and 1905 - Listings for both "Avenue Theatre" [[80 Woodward) and "Swan's Restaurant" [[87 Woodward)
1906 - Listings for "Avenue Theatre" [[80 Woodward), "Swan's Restaurant" [[87 Woodward) and the first listing appears for the "Socialist Labor Reading Room" [["Avenue Theatre Block").

The Socialist Labor Reading Room was also listed in the 1907 Directory but not in the 1908 edition.

My conclusion is that the earliest this photo could have been taken was in 1905 while the 1906 Directory was being prepared for publication. The latest it could have been taken was in 1906.

I also noticed that the 1905 Detroit Directory printed the ordinance that went into effect on Dec. 1, 1903 regarding the operation of automobiles within the city limits. The speed limit was set at 8 miles per hour "inside the 3/4 mile circle" and 12 mph "outside the 3/4 mile circle". It was also 8 mph on all boulevards and on any roadway within a park. Violators were subject to a fine not to exceed $100 and if they could not pay, they could be sentenced to a maximum of 3 months in the Detroit House of Corrections.

I doubt that 1906 Packard was going more than 8 mph on that Belle Isle roadway!.
