Day 270/365: Cassini Badges, not bumpf

My soon-to-be-retired line manager brought me a final crop of Cassini memorabilia. Pictured are badges, produced by the Jet Propulsion Laboratory, commemorating the following events along Cassini’s journey to Saturn:

1. The first Venus flyby (April 26, 1998)
   
2. The second Venus flyby (June 24, 1999)
   
3. Earth swingby (August 18, 1999)
   
4. The Jupiter flyby (December 30, 2000)

The lithograph is of some very old promotional artwork, also produced by JPL.
