Brian,

I have a piece of mint Guastavino acoustolith tile wrapped in a 
newspaper w/ the Katzenjammer kids... a fond remembrance to cartoon 
newspaper reading at my grandparent's house. BP is the only place that I 
think anyone would have a clue what this little artifact is for me.

Take solace in the fact that masons still lay bricks and were doing so 
pre-Great Pyramid.
