The first 7 episodes of the final season of Netflix's mega-hit show Stranger Things is currently streaming (the finale releases on New Year's Eve), and reader Steven M spotted a Rush Signals poster at the 27-minute mark of Episode 6 (Escape from Camazotz). The poster is seen on the door of the radio station where Eleven, Mike, Joyce and Hopper are strategizing their next move. Coincidentally, the line Hopper says as the poster is seen in the background is, Or ... we improve your signal. You can check it out right around the 27-minute mark of the episode here (subscription required). There have been a couple of other Rush references on the show - both occurring in Season 4. During the Season 4 premiere (Hellfire Club), right around the 11-minute mark, Jonathan Byers (Charlie Heaton) is dispersing pot smoke in his bedroom using Rush's debut album cover as seen here. Then in Episode 4 that same copy of Rush's debut album can be seen on the floor of Will's room as displayed in this screenshot
