Powered by and included USB cable, with On/Off switch to easily turn on/off LED back light! I have several of these almost identically autographed items, the pictures shown represent one of them. Although all of these are signed in almost the exact same spot, with the same pen, the unit you will receive may have a very slight difference in autograph placement and a different certificate. A Beckett authenticator/witness was present and issued witness certificates for each piece signed, each piece has been stickered with a tamper proof witness sticker with the certificate's unique number.
These unique numbers can be verified on the Beckett website. The item "Christopher Lloyd Back To The Future 2 Doc signed Time Circuits Prop Beckett PSA" is in sale since Friday, November 19, 2021.
