This Halloween Owl Pops bucket was produced by the E. Rosen Company of Providence, Rhode Island using waxed bucket blanks provided by the Lily-Tulip Corporation of New York, NY. We know that this was almost certainly produced before 1952 as Lily-Tulip moved their operation to Springfield, Missouri in that year. Rosen produced a number of ephemeral items with superb graphics in addition to what most collectors know them for - their Trix or Treats cards. If you collect Rosen items, this is a must have!
