In the drawing, there's nothing in the box (7)
I believe the answer is:
cartoon
'in the drawing' is the definition.
I can't judge whether this defines the answer.
'nothing in the box' is the wordplay.
'nothing' becomes 'O' (O resembles 0).
'in' indicates putting letters inside.
'the box' becomes 'carton' (carton is a kind of box).
'o' going inside 'carton' is 'CARTOON'.
'there's' acts as a link.
Can you help me to learn more?
(Other definitions for cartoon that I've seen before include "eg 'Tom & Jerry'" , "Drawing, maybe satirical" , "Humorous sketch" , "Jokey drawing" , "Comic drawing" .)
