I was recently given loads of old buttons, I've fished out a few that I might use, or just like the look of and have decided to sell the rest. I would guess that they've come from clearing a house after a death, hope that doesn't put anyone off! Or maybe just a move to a care home. They are all different and there are quite a few sets of four or more. I'm guessing at a date of 50s to 60s for most of them.
