Natural Light or a flashlight in a dark room (attached examples of both, note my phone isnt the newest so it will look even better with newer hardware) and a piece of black construction paper/dark color folder etc as the background. You can take some very nice photos this way.
Team issue postcard is natural light.
1971 Topps was taken in the dark with a light source (undergraded lol).
Both images are also cropped.
