Grey Wolf,
Thanks for the kind comments about my work. The prints you have are probably on several different papers, cranes 90# cover both natural and pearl, cot 320 and cranes wove which is no longer available. I am now using platine and cot 320 with oxalic acid pre-treatment. I have a Dick Arentz print that is on cranes platinotype that you can reach down into up to about your elbow, amazing!
