The "AZO" stampbox mark on the back with 4 triangles pointing upward was first used by the company in 1904. This comes from the standardized real photo postcard documenting chart.

What does the chart say about the divided back?

Not sure why this point is being repeatedly ignored here...

My understanding is that givided backs were legalized for US mail in 1907 when postal rules were liberalized to allow the writing of messages on the backs of postcards. An undivided back could be made any time; odds are that if the back is undivided and states that the back is for address only it is a pre-1908 card.

FWIW, my book says that postcards with the stampbox that has four right side up "Triangles in Corners" were first used in September of 1907.
