Just to prove feet come in all shapes and sizes, and degrees of hairiness, here are the feet of an arachnid.
In our original John Player reference book RB.17, they are described as "Small cards. A natural history series. Fronts in colour. Backs in grey with descriptive text. Home issue, July 1929"
This is one of a pair of sets, the other being "Struggles for Existence", which are very under-valued and truly fascinating, for they are the seldom seen subjects of the natural world, magnified, something that a scientist gets to see and work with every day but the general public would probably never get to see.
They are also descendants of the early lantern slides, which often featured small things expanded.
The truth is that like these cards much insect and animal life is also under-valued, but once you are allowed to really see how its parts function, and how beautiful it can be, hopefully you gain new respect for it.
