T206 Marquard "White Lines"

[sb1]

I have to disagree with this statement. The image quality on each and every card of the 150 series is far superior in color and sharpness than the 350 series.

By the time the massive 350 series was printed the stones were quite worn and reworked a bit I suspect.
As to the white lines and the doves, they were probably the results of effacing the stones.

The "Dove" in the sky that shows on some Ritchey's but not on others is the result of an improvement in the application or quality of ink in the 350 series printing. A person with more understanding of the printing process could possibly speak to the exact cause of the difference.

Both cards image quality improved during the 350 series.

I don't think this is the cause of the white lines on the Marquard though.
