Pictures designed to start illusion (13)

Ross

I believe the answer is:

illustrations

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

'pictures' is the definition.
(I've seen this before)

'designed to start illusion' is the wordplay.
'start illusion' can be anagrammed to 'ILLUSTRATIONS'.
Though, I am unsure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for illustrations that I've seen before include "Pictures (in a book)" , "drawings?" , "Examples" , "artwork" .)
