Absolutely! Anakat has done 2 for me and they are absolutely wonderful! But there are a few other good signature artists out there too. For anyone who thinks it's easy to create these things, I have photoshop at work and couldn't even work out how to put text over a photo, it takes some skill to be able to produce anything that looks good!
I agree they do make beautiful signatures. I think a lot of other signature makes do beautiful jobs as well. I really think that everyone has made his or her share of Rembrants when it comes to signatures. Everyone has had his or her Extraordinary moment making signatures.
