I know of several individuals who had arms rendered by Dennis - one of the world's foremost heraldic artists, and one with an instantly-recognizable style (he often produced "Celtic" versions of arms) - and I am pleased to have several versions of my own arms rendered by him in my own collection (http://davidwu10.drivinthebus.com).
Samples of Dennis' work may be seen on his section of the Society of Heraldic Arts website - www.heraldic-arts.com
We will naturally be posting more detailed information on The American College of Heraldry’s website, and will be noting this internationally-renowned heraldic artist’s passing in the next issue of “The Armiger’s News.”
