1970s Alien Tourist in San Francisco

Create a vertical 3:4 vintage-style street photograph set in a user-verified generic San Francisco neighborhood during the 1970s. Center one entirely original adult-coded extraterrestrial tourist: tall but human-scale, with elongated limbs, metallic sage-green skin, two oval eyes, small ears, and no resemblance to an existing character or creature design. Dress the visitor in oversized generic sunglasses, an original orange-and-teal floral shirt, and high-waisted brown trousers. It stands safely on a street corner holding an invented fold-out tourist map with abstract blocks, no real route, private data, logo, or readable business. Give the expression mild confusion and amusement without caricaturing any human culture. Build the background from period-appropriate but non-branded cues supplied by verified references—painted bay windows, overhead wires, parked generic cars, and adult pedestrians in original clothing—while avoiding a copied storefront or event. Use rich warm slide-film color, natural afternoon shadow, slight grain, mild color shift, and documentary framing. No named film stock, Haight-Ashbury business, real person, stereotype, celebrity, franchise, official map, fake historical claim, modern vehicle, logo, readable sign, text, or watermark.
