These archivists think this copy was made for Pennsylvania lawyer James Wilson, one of only six men to sign both the Declaration and the Constitution. If you've heard of him before it was probably as the poor schlub in "1776" who can't make up his mind how to vote. He was indeed ambivalent about independence, but during the debate over the Constitution he took a very strong position for national sovereignty:
