About I came across this particular treatment for swash caps in an old book on letterhead design. The original had been handlettered, but I though it might be convenient to have a ready-made font to accomplish the same effect, and here it is. As an extra added feature, the ?@? sign is an ampersand with a long tail.
The commercial font is “new and improved” over the freeware version, with expanded character set and improved kerning, so you get what you pay (or don’t pay) for.
