The "money lady" at the papyrus shop in Giza.
This shop is on a busy street near the pyramids about an hour outside of Cairo.
Paintings on papyrus are usually copies of various tomb paintings, and can be found all over Egypt,
but it is strictly "caveat emptor" when making a purchase,
Real papyrus paintings can be found in nicer shops and some hotel shops.
Other "papyrus" is often made of banana leaves or similar plants.
You get what you pay for !
