Issued by Germany (Deutsche Bundespost) in 1974, this striking semi-poster-style stamp promotes the life-saving importance of blood donation. The bold design features a vivid red blood drop alongside a blue medical symbol, creating a powerful visual contrast. The inscription “Blut spenden Leben retten” translates to “Donate blood, save lives,” reflecting public health awareness campaigns of the era. With its minimalist yet impactful graphic style, this stamp stands out among social-message issues. It is a fine collectible for thematic collectors focusing on medicine, public welfare, or humanitarian causes.
