A new special stamp was issued in October 2024 to mark the 150th anniversary of the Universal Postal Union. The design won the competition because it combines the idea of stylized envelopes and national flags, creating a colorful surface that vividly integrates the stamp lettering. In addition, the triangular flaps of the envelopes can also be read as arrows, which illustrate the transportation of the letters through the Universal Postal Union. The envelopes also reappear in the margin of the sheet of ten stamps and in the two corresponding first day postmarks. The stamp is available in Deutsche Post branches and online. The typeface Helvetica complements the minimalist style of the stamp.
