Flyer produced by artist during spell in jail (8)
I believe the answer is:
rainbird
'flyer' is the definition.
(birds fly)
'by artist during spell in jail' is the wordplay.
'by' says to put letters next to each other.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'during' becomes 'in' (e.g. during February means in February).
'spell in jail' becomes 'bird' (bird can mean time served in prison).
'ra'+'in' is 'rain'.
'rain'+'bird'='RAINBIRD'
'produced' acts as a link.
(Another definition for rainbird that I've seen is " Flighty type".)
