A great birthday card for fans of the Big Bang Theory. This card depicts the classic episode where Sheldon jumps up from the ball pit yelling Bazinga. Leonard and Sheldon are hand stamped, colored with alcohol markers, and cut out by hand. Leonard is adhered to the base and Sheldon is adhered to the slider mechanism. The ball pit is created from half inch circles punched out of cardstock and individually glued to a piece of cardstock which is then placed over Sheldon when the slider mechanism is down to hide him. The front of the card reads "I hope your birthday goes off with a bang". The inside of the card is blank. The card measures 4.25" x 5.5" and comes with a white envelope. It is shipped in a cellophane envelope and comes from a smoke free environment.
