These three paper toys are Bilbo Baggins, Gandalf and Gollum, based on the novel (also appears in same named film and video games) The Hobbit, which is a novel by J.R.R. Tolkien set in Middle-earth, the book was first published on 21 September 1937 and is set in the years 2941 to 2942 of the Third Age before the events of The Lord of the Rings. These papercrafts were created by Pop Quem.
Bilbo Baggins was a Hobbit, and the main protagonist in The Hobbit; he was hired by Thorin and Company to be their burglar on the Quest of Erebor, and he fought in the Battle of the Five Armies. He was also one of the bearers of the One Ring, and the first to voluntarily give it up to Gandalf, though with some difficulty. He wrote of his adventures in a book he called There and Back Again. Bilbo adopted his nephew Frodo Baggins after his father Drogo Baggins, Bilbo's second cousin ended up drowning in the Brandywine River; and not long after adopting the orphaned Frodo did he become the sole heir to Bag End. Bilbo was the first Hobbit to become famous in the world at large and one of the few to visit the The Undying Lands.
Gandalf the Grey, later known as Gandalf the White, also known as Olórin took the form of Men, but possessed much greater physical and mental power. For over 2,000 years, Gandalf worked most faithfully against the rising powers of evil in Middle-earth.
Gollum, originally known as Sméagol (or Trahald), was at first a Stoor, one of the three early hobbit-types. The name Gollum was derived from his disgusting gurgling, choking cough. His birth can be estimated to have happened in the year TA 2430. His death date is given as March 25, 3019. His life was extended far beyond its natural limits by the effects of possessing the One Ring. At the time of his death, Sméagol was about 589 years old, a remarkable age for a creature that was once a Hobbit, but he had been deformed and twisted in both body and mind by the corruption of the Ring. His chief desire was to possess the Ring that had enslaved him, and he pursued it for many years after Bilbo Baggins found it while walking in the Misty Mountains in the book "The Hobbit".
