Can I sell vintage pinup art on my online store?

I'm looking into possibly opening a Shopify site, but I sell a lot of pinup art including vintage photos, cartoons and magazines featuring both covered and topless women. I'm unsure whether these products are allowed. It's art, not porn.

I'm here trying to get an answer to the same question... My store, BUSH NYC, promotes the "70's BUSH" but for me, this is art, this is not porn. However, when I try to market the clothes without the nude women, they say the ad cant be processed.
