    Hah, good point!

    According to this, the first issue was Superman #59, from 1949, using his “X-Ray Vision”:

    And wasn’t until 1961 that it was explicitly referred to as “Heat Vision”.

    Which I guess makes sense, because the laser wasn’t invented until 1960.

    That being said, I’m not sure that that’s from the 1930s. That car has what I assume are supposed to be whitewall tires, which apparently existed in the 1930s but peaked in popularity in the 1950s. I’m no vintage car expert, but to me, the body styling looks more like what I get when I search for 1940s cars than either 1930s (cars were still boxier, didn’t have a streamlined appearance) or 1950s (loss of the protruding tire guards or whatever those are called).

    And I guess that the car alarm is probably anachronistic, but that that’s intentional.
