The panels are in a wax paper bag that is closed at the top with two heavy duty staples. We don't know if this packaging is after-market or original, so we left it in place. While we did not open it, it is safe to assume that this is not a master set and there is only one of each number - the bag is just not thick enough to hold every variation.

11/24 NOTE - This appears to be one series of 100 cards. We don't want to open the packaging but it looks like 25 sheets inside. With 4 cards per sheet that is 100. The red/yellow bag is known to the hobby and this appears to be an example of that.
