So who saves certificates of training, schools, appreciation.......?

Was wondering if anyone here saves all of their certifications received for training with the airlines? I admit to saving my certificates received in military and airlines. I like to look at them from time to time. Have certificates from Northwest Airlines, United, Continental, Continental Micronesia. (Northwest no longer exist, and Continental, and Continental Micronesia are called UNITED now.) Each with distinct logos some very cool looking, others quite lame. The real nice ones get laminated. I put them in a folder, but I need something to hold them better especially the laminated ones. I don't want to hang them up because, this house would look like a "Love me wall all around me". The military certificates are from technical schools and courses taken. I must have about six of those. Some have even turned a bit brown from the ages therefore, I laminate them now when I get them if they look cool enough to do it. So does anyone have airline certificates of training or accomplishments from now extinct airlines?

Ok......who has a piggy bank and saves pennies?
