Well I found something this morning whilst looking through the garage for something else. It was the stamps released by AUPOST to celebrate the centenary of cricket 1877 - 1977. This particular item is autographed by one of the greats of the game, Jeff Thompson. From memory, my Mother, who lined up for ages to get me this stamp set was told that less than 100 of the sets were autographed by Thommo. Here are the pics.
Here is a picture of the first day cover we also got on the first day of issue.
