Best R.M.S. leather

Product Name: Best R.M.S. leather
From the research I have done, R.M.S. was also known as the Queen's leather and best is lambskin. This hand woven, hand stitched paticular book/planner seems to be from 1912. The cellphone and business card holder were added later. You can tell because they are a different color, have different stitching and I think are different leather. There are several signs of wear as it is over 100 years old. No rips or tears tho. The spot where the tan has come off inside stands out most (pictured) 15x10.
