Life-sized "Water Well Key" item, from ASCII's 1993 Wizardry Side Story III: Scripture of the Dark Gameboy roleplaying video game.
This is one of several keys that the party must acquire during their adventures if they ever hope to succeed in their quest (original Japanese name: 井戸の鍵, which romanizes to "Ido no Kagi"; "ido" is Japanese for "water well", "kagi" means "key", and "no" is a particle denoting possession or a source). As you have doubtlessly gleaned from its name, said item opens a locked well, which can be found deep in the Southern forest. Removing the lid from said structure will then allow the party to enter a door that was previously unpassable, down on the sixth basement level of the nearby South Cave dungeon. The Water Well Key itself can be found on the first floor of the Temple, on an altar in a hidden chamber. When you first acquire it, the Water Well Key will be unidentified, just like all Wizardry items obtained in the field, and thus, just a generic-looking key with unknown properties, but, returning to town, and paying Mikela $100 to appraise it, or doing it yourself, for free, if one of your party members happens to be a Bishop, will reveal what it really is.
Here's a screenshot of the locked well (that I colored, as the original game is all in black and white). The romanized Japanese hiragana text says, "Kagi o ake ido no futa o torihazushita.", which I would translate as, "A key is needed to open the well's cover."
In the game, there's no image of the Water Well Key, so, all I had to work from was the name. I based my design, in part, on a real vintage key I own, as well as some photos of others that I clipped out of a magazine a long time ago to use as a visual reference for a project like this.
In keeping with the theme I started with the Wizardry Side Story IV: Throb of the Demon's Heart Gold Key (Kin no Kagi) item I made back in 2012, I wanted to incorporate the pair of kanji that means "water well" into the handle. Aside from looking cool, it virtually ensures that I'll never forget what the combination of those two characters mean. Speaking of which, I wanted to take a photo of the two of them together, but I'll be damned if I can remember where I put that Gold Key after I took my last group shot of all my Wizardry art projects. I also briefly considered modeling a cylindrical, brick-textured well for the key's handle, but, after making some sketches, it seemed awkward-looking to me, and it would have probably added unnecessary heft/bulk to the item (not to mention increasing the time needed to complete this piece).
Newsprint, cardboard, lined white paper, tissue paper, white glue, and acrylic paint.
8.3 cm (3.3") in length x 2.9 cm (1.1") in width at the widest part of the handle.
