How much do butters typically fade?

[AmericanTacos]

This is my butter pin as a tiny baby, his name is Pauly D


Here he is as a young adult, you can see how how his rich yellows have faded into soft cremes:


I also have a lesser girl (lesser and butter are the same), I'll try to remember to get a recent photo of her this weekend and add those.

So cute!!!! This has honestly just become a scheme to indulge my love for Butters

I would love to see the others if you remember!
