As a visual and conceptual artist , the box art is a huge attraction !
I'll be 43 in April ; I first started building in '73 or '74 , and my sole decisions for a 32nd scale snap kit was based upon what was on the box (Monogram's Funny Car series was my favourite !).
I ostensibly missed out on the golden era of box art (the Pop Art / Psychedelic artwork of '63-'70) , though I certainly do recall seeing those kits' boxes at older cousins' houses and in thrift stores and in outdated stock at dep't stores when I was a kid (wanted to build them , but they were beyond my abilities ...).
When I started on glue kits (around '75 / '76) I was drawn (no pun intended) to the MPC annuals . Sears seemed to keep quite a few of them in their stock !
Also , being of an abstract mind , the reissues of Tom Daniel's kits (Vandal , etc.) were a feast for the eyes !
In subsequent years , I've passed on many kits just because of the crappy cover art ! The RC-2 era of AMT was thee worst !!
In summary : The boxes' art still is a subliminal decisor for me , but not as big a deterrent as it was in the past .
The neuvaux Revell box art is attractive . Round2's box art is the absolute best (and , yes , that's in full recognition that some of it is repro AMT and MPC work , which is-was another favourite of mine !) .
