In Search on More Buttons

My local extensive button shop has these lovely buttons that I have bought. I pretty much bought her out of the small selection she has.
So, I have been looking on the Net for more buttons of this nature, but whenever I find some, they seem to be in these really cutsie shapes. I am looking for more like the ones I've photographed here. Anyone who can point me in the right direction?

I have a huge antique button collection, but I'd really like to use this style on some of my sweaters this year.
