HEY ... give Mastro credit:
because THEY even mention in their description that the cards are more likely from 1906 than 1904!!
Mastro has the game board and the original box and STILL CANNOT tell when exactly the cards were produced... so I think it is pretty safe to assume that they are from 1906 and NOT 1904.
