Artistic style and part of the old economy (4)
I believe the answer is:
deco
'artistic style' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'part of the old economy' is the wordplay.
'part of' indicates a hidden word.
'DECO' is hidden in the letters of 'old economy'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for deco that I've seen before include "Style of design popular in the 1920s and 1930s" , "Art -, C 20 style of ornamentation" , "Art's partner" .)
