Old (1980s) Plastic Musikfest Mugs Wanted

I'm looking for old Musikfest mugs to complete my personal collection and will pay top dollar for them. I need the yellow and/or white plastic mugs that were sold from 1984 to 1988. I posted a sample picture to show the style. They were not insulated and did not come with lids.

Please send me an email with what you have. If you are unsure of the year of a mug just send me a picture of it and I will tell you the year.

Thank you and have a great day.
