DENISON, Texas (KTEN) —  The Perrin Air Force Base Historical Museum has received two anonymous grants totaling more than $20,000.

The donations funded the purchase of eleven new kiosks which let visitors at the Denison museum take a self-guided tour.

Museum founder and board member Mary Day said the kiosks include include closed captions and audio in both English and Spanish.

"If we don't have a lot of volunteers on hand and we have a lot of visitors, they can use the kiosks instead of a person," she said. "It really helps us to have additional staff."

The museum is hosting a reception Saturday morning at 9 o'clock.
