On April 4, 2007, Ireland issued a stamp as part of a definitive series between 2004 and 2011. This 78c self-adhesive stamp in a booklet of 10 such stamps was dedicated to the “Black bog-rush”. On one of the stamps in the booklet was however imprinted “black Bog-rush” instead of “Black bog-rush”. The stamp’s position in the opened booklet was the to the right of the second row from the bottom. The booklet was withdrawn and replaced by a corrected version.
