Various Letterheads

Here are three different letterhead designs, I like this one because it looks very modern and contemporary, it uses little amount of colour and has a modern typeface .

This set of business stationary comes with business card, compliments slip and letter head. The logo is digitalized and circular, I believe it is kind of effective and stands out with the use of bold colour.

This letter head is very minimal, simple and subtle. They have used a light type face with light use of colour, there is a medium sized watermark in the bottom corner which is a nice touch.
