Set of 2 Vintage coffee mugs with primary colour design

Vintage 1980s coffee mugs with colourful toy design. One features a car and the other, a train. Both in primary colours. The design is present on both sides but colour arrangement is different on each side. Both have some shelf wear on bottom, due to normal wear and use. There are also a few stains inside. Overall very good vintage condition. No maker's marks. Each cup measures 3.5" tall and a bit over 3.25" in diameter.
