What kind of frame can I use to frame a poster WITH a drumhead in it as well?

I got my boyfriend a drumhead signed by one of his favorite bands for Christmas. I got a poster to go with it, and I want to display them together in a frame. I know I can get a regular poster frame but I don%26#039;t know if the drumhead will fit in a frame that thin. I%26#039;ve looked at shadow boxes but a lot of them are really expensive when you need one the size of a poster (24%26quot; by 36%26quot;). Does anyone know how else I could display these two items or where I could find a cheaper frame that would do the job as well??|||have you thought about building a shadow box yourself there pretty simple to buiild................. http://www.diynetwork.com/diy/shows_cds/...|||MICHAEL%26#039;S arts %26amp; crafts custom frame sizes, saw them there.
