Description

Item for sale is a vintage ELO (Electric Light Orchestra) "Secret Messages" promotional glass beer mug.  Glass is in excellent condition with no chips or cracks.  Measures 6" tall.  Please see pictures for full details.
Note: I believe the Secret Messages letters used to darken when exposed to cold, but this function has faded with age and the letters no longer change.
