The jacket shown here is one of the many props sold by the J Peterman Company back in the late 90's. It shows little to no physical wear but clearly has been discolored some. I'am assuming the discoloration is due to filming in water. The jackets sold by Peterman seem to be getting harder and harder to find. I purchased mine earlier this year and it came in the original Peterman shipping box along with the blue tissue paper and COA from Fox distributed by The J Peterman Co.
if you have any questions please feel free to ask and check out my other great Titanic items. One of which is the shoes worn by the elevator operator that appear in various scenes with actress Kate Winslet!
