I find this image interesting because, not only does it seem in comic form to prefigure the activities of Queer Tango London with the “Londoner Tango Club” having [albeit, uniformed soldiers, all men] same-sex couples dancing tango, those creating the postcard – which was presumably meant to encourage German Soldiers – judged that in, say 1914, the year after European “Tangomania” peaked, showing those soldiers wholly at ease dancing tango with one another might seem amusing, but not, apparently, threatening to their masculinities.”
