It is a "fantasy" item.
Though marbles were sold in gumball machines over the years, especially during the gum and sugar shortages of WWII and a little after, the gumball machines were branded with marble names like that.
Usually the machines were advertised as working for gum, toys or marbles. Not specializing in marbles. (I remember one machine for marbles from well before WWII, and I can't quite remember what it looked like, but it wasn't that, and in particular wasn't Akro.)
(So the machines labeled like that could be oldish but the labels were added later, probably after the machines stopped being used in stores.)
