The Grimshaw Studio exhibit has since been extended twice and currently remains on display, sharing space with the MC5 exhibit in the postmaster’s office.

The historical museum features the long-term exhibit, "Gary Grimshaw: the Master Artist’s Studio". Gary, who passed away in early 2014, was a native of Lincoln Park and a 1963 graduate of LP High School. Gary was a renowned and highly-respected poster illustrator who started his career in the mid-1960s at the same time the rock group, MC5, also from Lincoln Park, was spreading its wings. Gary was high school friends with Rob Tyner (Derminer), the lead singer for The MC5. The two friends were also fellow artists.
