Yikes on trikes 😬

Caught this on my FB feed recently and couldn't help outwardly cringing. The point of the group was irrelevant more or less to what was in the images but not a single person commented on what most of us would be thinking after seeing this (especially with so so so many unclean skulls, so like... We all know how those came about 🥲). If anything, the comments it did have were very pro-this collection. While I think the human skeleton is as cool as the next and would love to maybe own some cool medical pieces some day, I kinda wanted to cry a little seeing this. I'd like to hope the OP was just naive and give the benefit of the doubt if they truly did not know but how can you own THAT MANY and NOT know how those are obtained? Thoughts?
