Don't quote me on this, but I believe I read that you cannot get "true" ancient madder anymore because one or more of the original dyes used was found to be toxic. The only way to get the real deal is to go with vintage.
Spoo, I agree with AHS, that might be one of my favorite finds ever posted on this thread. Also, congrats on the opening of Luxswap! It looks really really great! Can't wait to make a pilgrimage out there one of these days.
