Display tawdry items also (6)
I believe the answer is:
tattoo
'display' is the definition.
(I have seen 'Military display ' mean 'tattoo' so perhaps 'display' could also mean 'tattoo')
'tawdry items also' is the wordplay.
'tawdry items' becomes 'tat'.
'also' becomes 'too' ('too' can be a synonym of 'also').
'tat'+'too'='TATTOO'
(Other definitions for tattoo that I've seen before include "Skin inking" , "Edinburgh military parade" , "Military display - picture on the skin" , "Example of body art" , "Skin design - military entertainment" .)
