Two Serbian Relief Fund charity postcards. Lecture booklet, 'The Spirit of the Serb' by R. W. Seton-Watson, who was the Honorary Secretary of the Serbian Relief Fund. Receipt for donation to the Serbian Relief Fund for the sum of £2, dated 19 November 1915. || The Serbian Relief Fund was a British charity that set up and maintained a number of hospital units in war-torn Serbia, that also worked in cooperation with the British Red Cross, and helped refugees. Here are a couple of their postcards that were part of the information and fund-raising campaign at the time. One card shows a photograph of a Serbian prisoner of war, suffering from typhus, in an Austrian prison hospital, and the other card is a reproduction of a painting of a Serbian prisoner of war, signed by Angeli Radovani.

Charity stamps were a good way of raising money and awareness for causes. Shown here are three charity stamps with a focus on providing help and relief to Serbia, as well as France. First is the 'Serbian War Orphans Fund', costing 1 cent. At the top, in Serbian Cyrillic is the text, 'СРПСКА РАТНА СИРОЧАД', which transliterates as 'Srpska Ratna Sirocad', and which translates to 'Serbian War Orphans'. The central motif shows ruins, children, a female figure, looking at the rays of the sun, and the words 'Humanity' within the rays. The address at the bottom of the stamp, 1905 Fowler Street, Chicago, Illinois, which is property of the Serbian Orthodox Church. Second is the Serbian Relief Fund stamp, which shows an image of a desolate Serbian soldier, below which is the text 'Begs Aid For Our Brave Ally', and the price of one penny. The Patroness of the Serbian Relief Fund was Britain’s own Queen Mary, its President the Lord Bishop of London, and Vice-Presidents included the Lord Bishop of Oxford, H.H. Asquith, W.S. Churchill, and Lloyd George. The work of the Fund included the establishment of a number of hospital units in Serbia, including some mobile ones, as well as sending nurses and medical supplies and stores, helping also the work of the Red Cross. Thirdly, is a stamp for the California Committee For Relief in Serbia and France, with a central figure of a nurse, above which is the text 'Merry Christmas', and the year 1919 below, and the text ‘California Committee for Relief in Serbia and France’ surrounding the central figure. The background has the Serbian tricolour of horizontal red-blue-white in the top half, and the French tricolor of vertical blue-white-red in the bottom half. This Californian stamp showed that, despite the war having been over for a year and more, clothing and other supplies were still needed and that, though California may have been half a world away, it was still going to help. || Three charity stamps. One for the Serbian War Orphans Fund, one for the Serbian Relief Fund, and one for the California Committee For Relief in Serbia and France.
