It was not fair. Every single year, all over the world almost every car parts company makes calendar with cars to offer the mechanics who buy parts from them.
And nobody had thought that fishermen also like to know what day of the week they are on, and would like to have their calendars with fish, instead of cars!
But that is an unfair thing that was corrected by a new Calendar! You can see next month image, but you can also see the full calendar (probably updated next year) in the Zebco website.
