Frida Kahlo disliked white capitalism intensely, so I wouldย recommend not buying images of her on socks or whatever from big box stores especially if youโre white.
What I would recommend instead is make your own art and design inspired by her. She taught underprivileged teenagers art in the years leading up to her death. Her class was multicultural due to Mexico accepting refugees from WW2 including Jewish people(she herself was half German Jewish). She was very pro DIY and I think wouldโve been flattered by fan art thatโs not sold for money.ย
