Definitely not my typical prop build, but my mother loves the 1963 film Charade, with Cary Grant and Audrey Hepburn. I'm not going to waste time putting a spoiler tag in this, but it's worth seeing if you haven't, and honestly the name of my thread kind of already gave away the twist of the flick.
ANYWAYS, I decided to duplicate the torn envelope with stamps to place in a shadow box for mom. To refresh, here are the stamps (all fictitious, but loosely based on real designs):

I've already duplicated the stamps (not so challenging), but the envelope is what is killing me. In the movie, it is a security envelope, but the 'security liner' appears to be a solid blue, not the repetitive scrollwork blue or red that seems to be used these days. The envelope is also not a standard size (for the US), but stubbier and taller, as you'd imagine what some greeting cards would be in. I'll be the first to say that, when I give this to my mother, she will not care in the slightest about the envelope type. Having said that though, I WILL KNOW, and there is no way I'll let that fly. I can custom make the envelope (the paper itself), and I guess I could print my own liner, but I was thinking perhaps I'm overlooking an easy source (or solution) to this problem? Any help that you guys could offer would be more than appreciated.
Here's a pic of the envelope (obviously pre-torn); unfortunately I don't have a screencap convenient of the security liner. I thought I saw those envelopes with the solid blue liner as a kid for perhaps airmail, but I also thought those were postage-paid?
