This is an exceedingly rare and desirable invitation produced by Dennison around 1930. The bonus is that is is unused. (Finding near-mint, unused small paper items like this one doesn’t happen as often as finding them ragged and written upon.) I like how the colors and the energy of the fighting cats contrast with the mellowness of the interior. This deserves to bring meaningful dollars.
