I think the 1st time I saw the head in the glass container on Sleepy Hollow, I thought "Well, I'm going to need to make one of those in 1/6 scale".
The glass is a seal-able jar, and the metal structure is all made with styrene plastic strips, painted and weathered with Doc O'Brien's weathering powders. The skull is from this awesome ebay seller , and is actually 1 of 10 that I ordered from them. And trust me, I know I'll find a use for all 10 skulls (11 actually, since they hooked me up with a bonus skull!).
The whole thing is a bit heavier than I'd like (poor Violet Rose can barely carry it) but it's a pretty minor complaint. Whose skull, and how it plays into the House of Seasons world is a story for another time.
