Vintage Dollhouse Miniature Mailbox Metal W/ Heart Decor For Front Porch 1:12. This listing is for a vintage miniature mailbox for a dollhouse. It is made of metal and is a beige color. There is a heart drawn on one side with, “welcome home” faintly written on it. It looks like something used to be glued inside, but now there is just leftover glue in there. This item is about 3 inches tall laying flat. There are scratches on the metal throughout from age. This item is in FAIR pre-owned condition. Thanks!
