The throwback picture also gives a glimpse of Kapoor's grand house.
"What is unique in this picture? In my living room, on the left side on the floor, is a young Ranbir reading comics," Rishi, 62, posted on Twitter.
The father-son duo last appeared together in "Besharam".
Ranbir is currently gearing up for his stint as a cage fighter in "Bombay Velvet", which will hit theatres on May 15.
