The image was shared on content-sharing platform Reddit with the caption “Found E.T.”
And indeed, on closer inspection, the figure does very much resemble the shape of loveable alien E.T from Steven Spielberg’s 1982 hit film E.T. the Extra-Terrestrial.
Therefore, it’s possible the figure is in fact simply a model or toy of the character.
A bust can also be seen further along the windowsill, perhaps further suggesting an artistic interior lies behind the glass.
