Preview of t-shirts

Hi, I’m filling my order for Turris Omnia and I’m asked about colors of t-shirts. I’ve tried to search the web but I didn’t find any relevant pictures of t-shirts. Can you please point me in the right direction or upload some pictures of color variations? I’m interested in both ‘old’ Turris t-shirt and the new one. Thank you.

This guy wears ‘old’ Turris t-shirt - It has gray color and also has CZ.NIC logo behind neck

Omnia t-shirt has similar design with few Turris Omnia logos on chest and behind neck and is in white color. For example in this video from Internet and technologies 15.2 (guy in white shirt at the beginning).
