Scroll down here and look at the bottom border !! Is yours the same ?? The small wording immediately below the pic is what I need to know !! Both left and right side !! The difference in dress color is due to the pic definition and some likely fading over the years !!
This is how it should be at the bottom for an original print !!

I guess it came through on Page 1 (rather large), At least I tried to scan it in.

Just do the best you can !! No problem !!!
