I came upon a the above picture of Emma Watson in a bright red (my favorite color) floral lace dress and it gave me an idea for a the card you see above. This is an original autograph card design of mine. I title the files I've done in this style as "slim autograph cards". Typically they're clean with a little stylizing and plenty of white space to make an autograph pop. This one turned out the way I pictured it in my head so I was pretty pleased with the end result.
To the best of my knowledge Emma Watson doesn't do much signing, but if she ever does do a private signing or something and it isn't a budget breaker I'll have a card ready to go.
