Hi Dave,

I would get copies of the two Time-Life books "Arms & Equipment of the Confederacy" and "Arms & Equipment of the Union" as both have lots of full color pictures of these flags that you could scan for the presentation.

For the Confederate side please visit our website Flags of the Confederacy at www.confederateflags.org for all of the msot up to date and accurate details of those flags. There is no corresponding site for Union flags. There were several Union flag makers and the Time-Life book has details of them and their patterns.
