I have placed the following Christianity and Christian apologetics related images into my CafePress site where you can purchase them upon t-shirts, stickers, etc.
Find my CafePress shop here.
Also, please spread the word about these as CafePress is a great outlet for reaching many but the sales commissions are not so great.
Here are a few examples of the images available:

A plea: I have to pay for server usage and have made all content on this website free and always will. I support my family on one income and do research, writing, videos, etc. as a hobby. If you can even spare $1.00 as a donation, please do so: it may not seem like much but if each person reading this would do so, even every now and then, it would add up and really, really help. Here is my donate/paypal page.
