A. Hank,
We would only create this framed design with a double mat. The second mat creates a platform for the stamp window thus protecting the print below.
You can see an example of a framed presentation of a framed Duck Stamp here. This presentation has the stamp opening off center to the right, but of course we can create this design centered as well.
A double matted and framed presentation with conservation mounting, conservation quality mats and glass would run approximately $185-240 depending upon the mat treatment and the moulding chosen. The frame pictured above would retail for $217.37
Please get back to me if I can be of further assistance. John Ranes
