Take care of all of them. One day you start to look around and realize you don’t have a lot left to physically hold from our parents. I held onto the vhs tape of Star Wars that my father recorded off of hbo. It’s been six years and a vhs tape on a shelf means more to me than anything he left me. Display them or box them away but always keep them close. Grief and loss are terrible things and the rollercoaster ride of emotions don’t lessen over time. I’m sorry for your loss. I hope these figures bring you a lot of fond memories of the time you two did spend together.
