It's time for Sunday Stamps. The theme this week is bizarre or unexplainable stamps.
The first one below, from the Netherlands, might have something to do with posting letters.
Or maybe not. The second one below I have posted before on my blog. It's from Lithuania.
A marble? A bead? No one knew then what it was trying to depict, and I am not sure either.
