halloween 13 anyone?

[Francoise]

i don't remember who ran this challenge way back whenever, but I loved it.

Starting today, there are 13 days until Halloween (inclusive, the mathematician in me must add).

Post your Halloween-inspired pictures with tag halloween13-2021

I posted this one last week so I’m not sure if if can be entered in this challenge. You don’t have a start date per se so I thought I’d throw it in there.
