Sweet! 당신 can bring the poster and the picture to the nearest 사진 Class (most likely at a highschool) and the teacher can do it for 당신 for a cheep price. I was in 사진 class and did that for me and jasper. It was pretty cool. I won best picture of the 년 award. My teacher said it was the best one he'd seen since he came to work here. Once there 사진 shopped together 당신 could bring it to festival. I know they put pictures of people on cakes all the time. I did for my great grandpa one year. 당신 could also try asking a professional cake decorater at any cake supply store. We have one here in WI but I'm not sure if she puts faces on cakes. I hope 당신 figure it out! She'll be so happy!
