A classic PSA mistake, here. Some of these World-War-One- era and early-1920s cards is EVEN dated on the back: "17th March 1921".
Yes, one of the cards shows a letter, from a boy, dated 1921.
So PSA took this clearly dated 1921 card and graded it as 1897!
Then unwary buyers pay more, I guess.
Similar cards were sold in an "Old J......" auction in USA. I wrote to both firms. No reply from either
