I suggest Big ant studios two important dates in December on either of which they can release to make the releasing date a memorable one !!
1) 4 December :- On 4 December 1936 Bradman captained Australia for the first time in a Test match v. England at Brisbane
2) 16 December :- On 16 December 1927 Bradman Shield debut vs SA in Adelaide. Originally picked as 12th man went into the team replacing Archie Jackson who developed a boil on his knee. Scored 118. SA Coach Patsy Hendren was also very impressed with his fielding.
