VTG 1986 Class of 86 Mug Papel 20 oz White Multicolor Rainbow Ceramic Coffee Cup

Vintage Papel Class of 86 Coffee Mug White with rainbow striped graphic Handle 20 fl oz capacity Ceramic Hand decorated There is no indication of whether it is microwave or dishwasher safe or not There is a 3/4" gouge on the side of the mug near the top rim. It does not go all the way through to the inside of the mug and I don't feel that it is in danger of worsening. Otherwise gently used condition with no other flaws that I can see.
