Hello Leon
Well this sort of fits that date but the lady is wearing a very stylised outfit.It appears she may have an early gigot sleeve to her bodice which would fit an 1893-5 date,her hat also.The boy's sailor suit was also popular throughout the 90's & well into the 20th.C.It's possible this could be early 20th.C so if you have the original can you rescan it in colour & show all of the cardstock & the back.
