Lasting exposures

We sometimes leave items in the attic
Don't plan to ever use again
An old brownie camera quit to click
Left abandoned in attic with shutter open

Throughout many years different home owners
Ignoringly left loft room neglected
Camera with open shutter kept taking pictures
Lasting exposures of ghostly images undetected

Uninvited phantom squatters occupied the roof
Ever since house built on burial ground
Today there's still no proof
That graves underneath could be found
