Top is an old promotional / advertising postcard from 1906, depicting the new grand stand (Nuttall Street Stand) at Ewood Park. Steelwork by John Booth & Sons of Bolton.
Below that, two players that would have been playing around the same time. The photo on the left was a postcard posted in Blackburn in 1907, but sadly I haven't been able to identify the player. The player on the right, I'm pretty sure is Eddie Latheron, who played for the Rovers between 1906 - 1917. If you know different, please let me know and I'll be happy to amend.
The cigarette 'silk' dates to the same period, perhaps a bit later, but pretty confident it would be pre- WW1.
The photo below is the same stand pictured 79 years later in 1985. I have forgotten where I sourced this photo, so if it's yours, my apologies in advance, just send me the details and I will be happy to credit you (or remove it).
The picture / card below added 30/06/2013 in response to BTS's query with regards Eddie Latherton (please see the comments below).
