Open Envelope with Blue Letter Inside

Here's a simple graphic depicting an open envelope, ready to reveal its contents. A blue sheet of paper, possibly a letter or document, is peeking out from inside, marked with faint horizontal lines that could represent written text. The envelope itself appears to be a light grey or white, with subtle shadows suggesting depth, giving the impression of a message waiting to be read.
