I'll put this here as I don't want to start another 6.0.3 thread, but I for one am excited about this release!  I searched the internet for quite a while and never found any pictures of what actual System 6 IIgs diskettes looked like.  Finally, I found a poor, very compressed image on a French website.  That same site also listed the Apple part numbers:

 
Apple IIgs System Disk, Version 6.0, Ref 690-8300-A 
Apple IIgs Install Disk, Version 6.0, Ref 690-8301-A 
Apple IIgs System Tools1 Disk, Version 6.0, Ref 690-8302-A 
Apple IIgs System Tools2 Disk, Version 6.0, Ref 690-8303-A 
Apple IIgs Fonts Disk, Version 6.0, Ref 690-8304-A 
Apple IIgs synthLAB, Version 6.0, , Ref 690-0134-A 
 
Using this info, I made some recreations of the labels and printed them out.  Of course, I can't verify if this is how actual disks looked back in the day, but if the French are to be believed, it looks pretty good to me!
