Conceptual vector design is split into two opposite categories, the vectors that are funny, transmit a humorous message and are likely to end up on T-shirts and the ones that send a concerning message regarding an issue or are motivational. The biggest proportion of these two categories is represented by the comic ones, of course. Life is usually pretty rough and having silly moments or enjoying silly things helps you get over difficult times.
I hope you will enjoy these fine examples of vector art and if you really like them you can buy a T-shirt print, where available, or posters featuring these designs. You can surely get any size for the posters considering they are scalable so if you plan on having a wall-sized vector poster, there’s nothing that can stop you.
