St. Vincent commemorates deep space probes past, present, and future, along with Carl Sagan and SETI@Home in a series.

I wonder when or if the US will commemortate Sagan on one of its own stamps?
It is not every day that you see SETI commemorated on a stamp, either.
The series also commemorates past, present, and future deep space probes. It looks a little cheesy, but I have seen far worse and less accurate.
