I have a question.

So I was wondering, if I walked into an anime convention and asked a VA for their autograph on a shirt and it had a picture(s) like this one http://funnymama.com/store/120906/106374_v0_600x.jpg or this one though imagine it had subs on ithttp://farm4.staticflickr.com/3594/3577241595_bff4756532_z.jpg?zz=1 do you think that there might be any issues due to....somewhat obvious copyright stuff? As in pulled straight from a show(that they voiced) and placed on a tshirt that I'm asking them to sign
