Hello all,
I am documenting my collection in an Access database and came across an item that I cannot seem to identify on any site. Just looking to get a rough market value. It's the Scott 741 2c National Parks Grand Canyon stamp but it is only perforated on the top and sides. The bottom is imperforate.

It appears to be part of a booklet?? Did the Scott 741 come in this configuration or is it a fake? Thanks for your advice.
Lou
