We have done that on some of our decoupage to keep moisture out. It might give it an amber tint though.
If you thought the tint would be undesirable (though it probably would enhance the cards like an antique patina) you could cover with plexiglass or clear contact or some similar protective sheeting.
I think Hunter Hampton has pictures mounted in the flush part of her raised panel overhead cabinets (where some have mirrors) and some wall treatments. Nice effect.
