Tango Seul is the official ball of the 1988 Summer Olympics. The construction of this ball does not differ from that of Tango Europa 1984. As you remember, it was the first ball ever created specifically for the Euro Cup. These balls are practically the same. We can only note the presence of the 1988 Olympics logo and traditional Olympic rings.
Then it was still monochrome patterns, but it was not long before a century of incredibly bright and colorful soccer balls.
