I believe this originally sold for $15.00. After 20+ years I'd suspect the PA Capitol Preservation Committee is trying to get rid of the remaining stock, which means they either have a ton of them to sell or they're trying to sell off the last few copies. In any case, it is an excellent resource and if you are interested, you probably should go ahead and order it.

BTW, the two-volume set on PA's Civil War Flags, "Advance the Colors," is down to $14.95 for the set; that, too is a big reduction from the original cost. Also available, if interested, the book "Pennsylvania in the Spanish-American War" is still available for $7.95, and includes photos and info about the Pennsylvania flags from that war as well.
