What happened to the Stand Ups?

When cartoons were (or sometimes today too) promoted, often the creator and/or voice actor will take a promotional picture with these stand up cardboard cut-outs. Where are they now? I imagine they were thrown away but are we sure? Where did they make these? What did they exactly do with them. Anyways, the major one if you look is Hanna Barbera. This especially comes to mind with the Flintstones. There are a ton of photos with Mel Blanc and Barney Rubble. So many that I'm not going to even try to put them all here. Anyways, what did they do with them afterwards? Did they throw it away? I see them in the back of recording session photos like a few below but was that also for publicity? I don't know... do you?
