It's a fairly basic presure sensitive label, I think it can be printed on a home printer or at a print shop like Office Depot (you'll probably get better resolution at a print shop). Windows Photo Printer prints in 4" x 6" (x2) which is the exact size of this label.
I can also send a high res PDF to anyone with crop marks if they're interested. I just couldn't find a way to post it anywhere here.
