A client cannot provide a vector image, nor recall the font used on their logo. Only a low-res jpg exists. Can someone assist me, please?

It shares a few features with Zapfino, but it's definitely not. Thanks!

"all a's" and "d" and "f" are "Zapfino One"...
"r" and "C" are "Zapfino Two"...
"n" is "Zapfino Three"...
"G" is "Zapfino Four"...
"e" is "Zapfino Alternate"...

Simply amazing! Thank you!! I hadn't realized Zapfino was such deep font set, till now. -B
