Electronic Recording Postcard

I bought this at Target in 2003 - it is a postcard, with a place to write, put address, and place for a stamp on the back.

Here are the instructions written on the reverse:
1. Slide power Switch to On
2. Hold the Record Button to Record
3. Speak into the Mic (10 seconds)
4. Press Play to Listen to your Message
5. Slide Power Switch to off for mailing
6. To Change Message...Repeat Steps 1-3

the card is about 1/2 inch thick and is unused ( I left it in the original package with the tag it was hanging from - was $4.99 on sale for $3.48 - Designed by Idea Nuova, Inc. For Target Corporation)
