There are three styles of Halloween decor: the fun stylized stuff, the gory zombie stuff, and the realistic creepy stuff. My Halloween decor at Lunaria Emporium on Wolf Territories Grid is definitely the latter and I have a nice collection of both original and curated items not available anywhere else in Opensim. You can find it on its own display area at the Emporium. Click the Gothic sign on the left as you enter the store lobby. The eep pictured above is what you will see as you enter the area if you have shared environment activated.

All of it is also available on the Kitely Market here: https://www.kitely.com/market?store=13957705&q=cemetery
