[Award Winner ] Creating an old-school map in Gimp.

[RobA]

I'd think, yes. It was to prevent copying.

So did TSR really produce those maps in nonphoto blue to prevent xeroxing [...]

Yeah. For similar reasons, they did many runs of the official AD&D character sheets on paper with a fairly heavy orangey-browney background that was difficult to photocopy (without great care it would produce a muddy swamp of grey mess), and in some later things they used red screens for similar reasons, since red photocopies as almost-black.

I'm just glad they grew out of their "Blue Period" in time to do awesome maps like the I6: Ravenloft plans

OH man I6 RULED as a map when it came out ... I LOVED that map and it was a fun (?deadly?) adventure too... but I sooo fell in love with that map... we should have a gimp tutorial on creating one of those maps!! ... probably be easier in Illustrator tho ... more than PS or GIMP ... or actually I imagine that you could knock one out in Google Draw pretty quick...

nophoto blue... the earliest form of anti-piracy protection ... you can't hardly find any nophoto blue pencils or anthing like that anymore.. I know.. I've tried on a number of occasions in the past couple years.. I finally gave up ... just sketch with some blue colored pencils...

It is, yes.
