“Year of Volunteers 2001” stamp sheet, issued by Australia Post, features ten 45c stamps, notable for their lower postage value compared to the sales price. The set was made available to charities at AU$12, with the intention of selling them to the public at AU$16, resulting in a AU$4 contribution per sheet to the designated charity . The sheet included an image of a Salvationist, though the specific identity of the individual is unknown. Limited edition (Source: SAPCJ 2002, 42: 668). There is no confirmed date of issue, and I’m not aware of any letters affixed with these stamps.
