I remember Nora's first postcard - which she sent in an envelope secretly to my office.

"And they sent this how, in a nice envelope?"

Otherwise, use two or more cards, attach entry token to the top postcard and send them to us in an envelope.

The reservation was sent along in an envelope and Larry made the train gate with five minutes to spare.

An operator said that Lou could send the coupons in an ordinary envelope with a signed W-9 tax form.

Please spare my copies in future by sending them in a pale pink envelope with flowers on.

Please be discreet and send it in an envelope by the bearer.

Any other correspondence should be sent in a separate envelope.

But the directive applied to all registration forms, even those sent in an envelope or delivered by hand.

Preferably they should be sent in an envelope which does not contain any other items of correspondence destined for our office.
