This version of "Jack-O-Lantern of Plenty" was available free in the Market Place (/market) on October 29, 2011, as part of a 4-day one-item-free-a-day Halloween event.
This is different from the version of "Jack-O-Lantern of Plenty" previously available for purchase for 200 Station Cash.
You can tell them apart because the free one is Lore while the non-free one is not lore.
