You will receive all of the keys shown in the photograph - 24 in total. Most of the keys are between 2 to 2.75 inches tall. You can check the ruler on the last two photos for size.
I post the very next day after purchase (unless it's a Sunday).
There are other vintage and antique keys and supplies in my shop: http://www.etsy.com/shop/chanchala
