Purpose of B18 Blankets

[bbnut]

I saw the original post on twitter some months back, and the one today, and I said both times, that I don't buy it. I would want to see some provenance.

Back during that time, they had fountain pens (pens with a reservoir), and nib pens (sometimes called dip pens). You don't want to use fabric to help clean off a fountain pen because the fabric strands can get into the capillary system and clog it up. Paper--or today, paper towels--is a good way to get the excess ink off the pen when you're done using it, which you want to do because the excess ink can potentially clog the system or cause a mess.

It wouldn't be the first time a historical society or museum screwed up something like this. We only have to look at the location of the Baseball Hall of Fame, and Doubleday Field for an example (although, as we know, that was done deliberately).
