So my photographic endeavors had drug me right back to the forums I've found myself in quite the pickle and need some help from anyone who can lend it, if you could I've been in search of some backdrops for my photography, but cannot find some good sources to purchase from for the following-

Tiger Slate
Black Slate
Rustic Gold Slate

I'm looking for a 12" x 12" piece of each or so. Most of the sites I've come across were junk, outdated with no real pricing, or they sold them by the pallet

If anyone could help me out with some sources or anything, so I can finally get some purchased, it'd be greatly appreciated!! I've checked Home Depot, Lowes, and The Andersons, and did get some good backgrounds for my inverts and reptiles, but still need these. Could anyone help a brotha out?
