The A.S.C. description (page 77) will be paraphrased: They were issued on June 26, 1897 [but Stanley Gibbons states that the lower value was issued on June 22 and the higher value on June 28] to raise funds for the Queen Victoria Homes for Consumptives" [tuberculosis, which was more prevalent in those times]. The 60th Anniversary of her reign was greeted with enthusiasm and the citizens wanted to commemorate her reign by a philanthropic service project. The various hospitals for consumptives were in need of funds.
Under the patronage of the wife of the N.S.W. Governor (Viscountess Hamden) a committee of influential people requested that the Postmaster General of N.S.W. (Mr. Brinker) issue postage stamps 'surcharged' to raise funds, the request being made in late May, 1897. After some debate, it was agreed to issue a stamp with a postage value of 1d, with an additional 1/-, and a 2½d with an additional 2/6d, both charity charges being considerable in 1897. The stamps were issued in sheets of 40, and the sales period was set as 2 months. The quantities issued were as follows: 1d 40,000 and 2½d 10,000. The initial sales were slow and were never popular with the general public.
However, the organizing committee from the Queen Victorian Home for Consumptives acted as a broker to stimulate sales to business firms of Sydney and the sales were eventually a major fund raiser for the Fund with a profit of £2,928/16/6d. The profit realised is consistent with all the stamps being sold. No additional charity stamps were produced in either N.S.W. or Victoria after these 1897 issues.
The 1d plus 1/- stamp portrayed "an angel supporting an exhausted human being with a portrait of Queen Victoria in the upper right. Across the top appears the inscription 'Consumptive Home'" (Figure 1).
