Ireland's two November 6, 2014 computer-vended Christmas stamps feature stained glass. They were produced in coiled rolls of 600 se-tenant, or alternating design labels. When purchased and imprinted in black, the labels are numbered in the lower right corner facing inward, sideways (1 and 306 on these ).
From the www.ateeme.net
website, "The two designs for the SOAR (stamps on a roll) issues feature details of stained glass windows created, or inspired, by the work of Harry Clarke (1889-1931), Ireland's greatest stained glass artist."
