So far only 3 different hologram designs have been used on the labels. Those labels still available (plus the withdrawn Christmas labels) have a hologram .39 x .39 inch (1x1 cm) in size. It depicts music notes, music keys and the word „valid“ (see below) .

The Easter design hologram was the same size ( .39 x .39 inch) but was stamp-shaped and depicted a single German postal service logo (see below).
 
 

Since the introduction of non-topical parcel labels (see page 48) a 3rd hologram was introduced. It has the same size as the above holograms ( .39 x .39 inch) but once again has rounded corners and depicts a single German postal service logo (see below).
