   There were also early practitioners, I can't name names
right now, who stripped the emulsion from glass plates and
assembled it on a final support. Some very complex pictures
were made this way. A similar stripping and assembly method
was used to make printing plates for decades.

   BTW, the Photo History list has been reactivated. I am
copying below the commands for this list. This might be a
good place to post this question.

     PhotoHist-l LISTSERV OPERATING INSTRUCTIONS:

                        To SIGNOFF or UNSUBSCRIBE:

1. In a message addressed to:
LISTSERV@listserver.isc.rit.edu
2. Send the following request: SIGNOFF PhotoHist-L

Nothing else. No name, no e-mail, and no signature files.
Just that one line!

You would also send other "command-type" messages to the
above address:

       SUB PhotoHist-L your-name-here (subscribes you to the
list)
       SET PhotoHist-L MAIL DIGEST (mail in digest mode =
index + text)
       SET PhotoHist-L MAIL POSTPONE (suspends mail
delivery)
       SET PhotoHist-L MAIL ACK (reactivates piecemeal
mail delivery)
       HELP (sends you a HELP
file)
