Image conjured by small literary house (5)
I believe the answer is:
litho
'image' is the definition.
(I've seen this before)
'small literary house' is the wordplay.
'small literary' becomes 'lit' (short for literary or literature; 'small' asks for a short form).
'house' becomes 'ho' (abbreviation for house).
'lit'+'ho'='LITHO'
'conjured by' acts as a link.
(Other definitions for litho that I've seen before include "Image" , "print in short form" , "work of artist" , "Method of printing using treated plate" , "work of art" .)
