These models were made between 1810-1830.
Biomedical Ephemera says:
It’s unknown if these models were intended as a darkly comic “memento mori” sort of novelty, or a teaching aid, or both.
The skeletons are accurate enough to have been used to teach students how the articulations line up in the living body, so even as a novelty, they may have had an educational use.
Even half dead and sliced open, about to be passed around between medical students like a bong, these darling little models still had time to get dressed up. How wonderfully deranged their priorities must have been.
