Hello Wayne, I am a complete novice and whilst I enjoyed the picture my memory of my parents pictures, that really were sepia, is that they were much less golden and no where near as sharp! I hope this is constructive and not negative.
I have a good collection of postcards ranging in time frames from the late 1920's to the mid 60's and even with color fade, many of them are sharp as a tack. A lot of what causes the OOF look to old magazine, poster or postcard images depended greatly upon the dot screen used in the photogravure process and the quality of the paper used.
Cameras in the 30's to mid 80's were quite good, and remarkably, still are. I'd pit many of the old Leicas against pretty much anything out on the market today.
I do agree to the image having too much a yellow color cast and would tend more toward a good speia.
Thanks Johnny, interesting.
