Look for gold American brochure (10)
I believe the answer is:
prospectus
'brochure' is the definition.
(I've seen this before)
'look for gold american' is the wordplay.
'look for gold' becomes 'prospect' (I can't explain this - if you can you should give a lot more credence to this answer).
'american' becomes 'US' (United States).
'prospect'+'us'='PROSPECTUS'
Can you help me to learn more?
(Other definitions for prospectus that I've seen before include "Brochure giving details of college courses etc" , "Advertising booklet for school or university" , "University entering opportunities for success in brochure" , "Promotional booklet" , "Outline plan for approval" .)
