The 1987 vault at the EPF base has a lot of pop culture artifacts from that year. Freddy Krueger's hat and glove from A Nightmare on Elm Street 3: Dream Warriors (1987), Geordi's visor from Star Trek: The Next Generation (1987), a Teddy Ruxpin teddy bear from The Adventures of Teddy Ruxpin (1987), Robocop's helmet from RoboCop (1987).
Bebop's union membership card is signed by "president" James Avery and "secretary" Pat Fraley. These are the voice actors for Shredder and Krang, respectively, in the original Teenage Mutant Ninja Turtles (1987) animated series. When presenting the card, the modern-day Bebop even says, "This isn't 1987. We have rights."
