I'm a little stuck... Click here to teach me more about this clue!

'small illustration' is the definition.
(abbreviation for figure)

I don't understand the remainder of the clue.

(Other definitions for fig that I've seen before include "Tree whose leaf may cover nudity" , "Kind of tree in effigy" , "something unimportant" , "Sweet fleshy fruit, often dried" , "Fruit with lots of seeds" .)

I've seen this clue in the Evening Standard.
