7/8" which includes W&H backpaper documenting to 1896. Beautiful color depiction of hand holding small camera with block text "You Press The Button - We Do The Rest." Button does not actually have the word "Kodak" on it but this is certainly their product advertising button. Button is a superior essentially Mint example although at the upper left there is a hairline of black crossing over the letters forming "You Press" although this line shows only under the closest inspection and is as made. Button has wonderful gloss and is totally clean with equally fresh pink backpaper from W&H. The best example we've had in many years. Historic and rare in this condition.
