In order of appearance…
Scanty Sophie is a ComicCon 2003 special silver CG01. $20.00 at Echobase Toys.
The book wyrm is a felted Chinese dragon. $200.00-$300.00, probably commissioned via etsy.
The library assistant is a Dollmore Melissa Hon BJD. $234.00 at Dollmore.
The head librarian is probably a square-jawed Obitsu head [W-03] on an Obitsu slender male body. Head is $6.99 and body $20.99 at JunkySpot.
The ghost is a Elfdoll Doona Ryung with the open-eyed head, preferably on a Notdoll Miriam body. Elfdoll Doona Ryung is somewhere between $340.00-$380.00 on the secondary market, while Notdoll Mariam is $310.00 at Notdoll.
The special collections assistant is a Elfdoll Doona Ryung squinty head, preferably on a resin [SoulDoll? Alchemico Labo?] 27cm male body. Prices for resin 27cm male bodies are unknown, as they are very rare.
The "little fucker" would be a DreamHigh Squee. $160.00 from Luxour Academy.
The sets would probably be comparatively cheap and easy!
The digitally rendered scene would serve as the exterior.
The book wyrm’s room could just be a corner of grey foamcore, maybe with some painted cardboard tubing for a few pillars.
The Pierian Spring would be more grey foamcore for the backdrop, more cardboard tubing for pillars, painted pie tins and other shallow vessels for the fountain tiers.
The Discard Bin could just be suggested by one coffin and ye olde grey backdrop with a rose window drawn on it.
The ILL center could be ye olde grey background with colorful, grungy window frames drawn on and some computers added.
A set of stacks could be made with two large bookcases full up, facing, making an aisle between them. Making each book out of paper and wood would take the most time.
Why am I spending so much time on this idea? It’ll never reach fruition.
