Relativity by M.C. Escher

That must be the Lithograph of Relativity 

of Endless Staircase by M.C. Escher the Dutch Artist. 

Relativity was first printed in December 1953. 

Look! There's the endless Staircase in 

the Live Action Movie called "Labyrinth" and 

My Life as a Teenage Robot Episode called 

"Around the World in 80 Pieces" was when 

Jenny Wakeman, Brad Carbunkle, Sheldon Lee, and Tuck Carbunkle were looking for 

in a strange Castle. 

Wait a second!
I didn't know there was an endless Staircase from Relativity by M.C. Escher 

in the Haunted Mansion in Walt Disney World was added in 2007!
