If you took the trouble, why did you post samples instead of full-size scans?
You call 12X19 sample size? If this is just a sample then I dont want to know what size the full scan is.
Also, I suppose theres a website unknown to me somewhere in the vast comos of the internet that offers said scans, but reverse google image search does not reveal it to me. And as a noob, thats all I got.
