I am the !#$%^&! guy that does the globes. Again, bad info. on here. The dates can be removed if you can grind and polish glass. They are etched deep and would leave a bad flat spot that would be very visible if removed. I wish people would talk to me instead of going on hear-say. It is easier to leave the dates off . I think the next run will be UNDATED and you guys can thank Lastgas15 and a few others for that. You should mind your own business if you don't know what you are talking about. Do you have any experience etching glass? Thank You, Steve
