This Back To The Future t-shirt shows Doc Brown’s DeLorean and the clock from the Hill Valley clock tower highlighted in cool colors. The shirt read 1.21 Gigawatts and 88 MPH.
In 1985, Doc Brown built a time machine out of a DeLorean, and when Marty McFly drove the car past 88 miles per hour, he was sent back in time to the year 1955. The only way that Marty could get back to the year 1985 was from the 1.21 gigawatts of electricity generated from the bolt of lightning that hit the Hill Valley clock tower.
You’ll have everyone saying “Great Scott!” when you wear this Vintage 1.21 Gigawatts Back To The Future T-Shirt!
