Vintage 1966 Snoopy On His Doghouse Blinking Christmas Lights Pin. There is a black toggle switch on the back to turn on the blinking lights. The lights work! And I just put in brand new batteries for you. There are some very faint black marks on the white parts of Snoopy due to age and storage (see the photos and the video). Great condition for a 1966 item. Nice gift for Christmas or for the Snoopy lover! Measures 2 3/4“ high.
