Prospectus (8)
I believe the answer is:
brochure
'prospectus' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for brochure that I've seen before include "Promotional booklet" , "Booklet or pamphlet containing information" , "Advertising booklet" , "Advertising pamphlet" , "Prospectus" .)
