These are not the original logos but in the spirit of contributing to the cause, I'd like to offer something that might be of help.
Back when I dabbled in graphic design, I remixed our logo using different typefonts, and I thought it might come in handy for anyone looking to design the shirts.
Feel free to modify it, enhance it, or use it as-is, or not at all – it's entirely up to you.
btw the original logo can be view here :
