Self promotion idea. Notice on the bottom slide, the letterpress impression of the glasses? You could get a die made of your logo or you could use your company seal - to put an imprint on everything you send out. Nice subtle way of branding.
Too modern for your purposes, but again, lots of space if given to the text - clarity and simplicity. The colour palette is also minimal but the block colours are really effective at dividing the brochure up.
