I have been interested in Giants and the alleged cover-up by the Smithsonian for a while. Finally did some digging through some newspaper archives and found some interesting stuff, several of which mentioned items being sent to the Smithsonian for “further study”.
Apparently, it seems like there are still many people that believe ‘Snopes’. In the list below, several articles specifically mention the Smithsonian Institution which has been accused of destroying/covering up evidence of giant human/humanoid remains.
