First of all... does everyone recommend Mashburns book to help identify postcard processes such as real picture, albumen, hand tinted etc., or is that book specifically for identifying prices? I am interested in obtaining a book that will educate me in the different types of PCs.
I have googled hand tinted PCs but I can't seem to find much on how to indentify them... most of the hits were only items for sale, not much educational information, so I have posted several pictures for your expert knowledge....
This first item I am guessing is a family picture. It reads "Lydia (?) picking violets May 16, 1902. L.S.B."
I'm not sure, but this appears to be "hand tinted" by the original photographer or owner. But then, it also looks like it could have also been painted in with felt markers at a much later date. What are your thoughts? Not sure of the value here...

Then I have this one that I'm almost sure is hand tinted because of the the consistancty of colors, pink and yellow throughout.

But then there are these two... because I am unsure of how hand tinteds are produced (any info from you folks would be much appreciated!) , I am unable to identify them... the first pic below looks like a possible photo that has been colorized... then the second looks like basicly color art work...

(Hand tinted photo ?)

(Not a photo - artwork only?)
I'm surprised there isn't more info on the web other than the basics in how to identify PCs. If you can direct me to better links than the basics or a very good book, I would appreciate it!
