Query: A `nice' bijection for a content formula for skew semistandard Young
  tableaux   Based on Sch\"utzenberger's evacuation and a modification of jeu de taquin,
we give a bijective proof of an identity connecting the generating function of
reverse semistandard Young tableaux with bounded entries with the generating
function of all semistandard Young tableaux. This solves Exercise 7.102 b of
Richard Stanley's book `Enumerative Combinatorics 2'.
