I have a number of mugs for Celtic matches. Jack Boyle kindly sent a scan of a mug for the Croatia Zagreb Champions League Qualifier match in 1998.
The Manchester United , Barcelona, Liverpool and Uefa Cup Final mugs were sold in Celtic shops as Celtic merchandise. The Croata Zagreb mug has date of away leg in Croatia.
The mug for the Jimmy Phillips testimonial match in 1998 was not sold in Celtic shops as far as I know. It is possibly a Bolton issue.
The Champions League Group 2004/5 mug is unofficial.
An Official Newcastle United FC Merchandise mug for the Alan Shearer testimonial match on 11th May 2006 Newcastle United was available but sold out quickly.
Latest on page is the Official merchandise mug for Celtic Manchester United Champions League ties 2006/07.
The photographs shows different angles of the mugs.
