I know that this is probably fake. I have had this since I was a kid. Pretty sure it came from my grandfather. I dug it out after I saw a recent news article about a guy in VT that discovered that one he has been lugging around for years and then found out it was real. These stories always get me excited. I cruised google looking for specifics on these and most of the ones I see have COPY stamped on them. Mine is not stamped. So like I said, I am sure it just came from a gift shop in Philly or something. But how is that determined? Anyone on here know about these and what the biggest tip off is to see if it is real or fake? Tip off #1 - it's condition? (too good)
