One Vintage Halloween ROSEN 50s Trix or Treats SKELETON MOON DANCE sucker card

As is so often the case when an auction ends at a puzzlingly high price, the unsustainable ending price of $142.50 for this smile-inducing Rosen Trix or Treats cards was brought on by two determined bidders. Remove the underbidder from the equation and this would have ended right around where it should have ended, $76.
Readers, for items like these cards that surface regularly, never pay more than right around guide value, which is $70. Although I do think this is the single best Halloween card Rosen issued, why pay such a premium? Sit back and be patient - for one will surface again soon enough.

Rosen made three distinct sets of their Trix or Treats cards. Set A consists of six cards, while Sets B and C consist of five cards. This is a card from Set B, the best of the three sets, produced during the late 1940s into the early 1950s. The RSIN for any one from this set is 3 and guide value is $70.
