Any ideas on this one yall? I have boxes and boxes of these type of bottles, my grandfather and great Uncles owned a very large construction company. Back in the early 60's the city of Houston contracted them to dig up the old Houston city dump. After they dug down about 15 feet, the dig stopped as to what they were digging up. The city of Houston shut the work down and called in an archeological dig team to excavate. Not before my grandfather and uncles made off with some of loot lol.
