I have an old 1950s Penguin edition of Marion Brown's Southern Cook Book. I love this thing. The newer editions have been rewritten and are missing several recipes. I have been looking on eBay for a replacement and it seems hard to find. My old Penguin edition is past yellowed--it's caramel-colored. It is coming out of the binding. Is it too far gone to laminate? Will it continue to decay inside the lamination? Does anyone know about this? Am I nuts to even contemplate it?
