Logo, insignia (6)
I believe the answer is:
emblem
I believe this is a double definition.
'logo' is the first definition.
(a logo is a company emblem)
'insignia' is the second definition.
(I've seen this before)
(Other definitions for emblem that I've seen before include "Symbol; heraldic device" , "Symbolic device or badge" , "Visible symbol of an abstract idea" , "Symbolic representation on badge etc" , "Device, badge or symbol" .)
