I do not have an interest to play card games though I did play those cards for social reasons.
Most of the time, the cards has the standard vintage patterns. Some people will collect litmited edition cards from different companies. These limited edition cards has more interesting designs to reflect the brand of the company.
I was scrolling through Pexels for an image for my journal, and I saw this playing cards shot by a photographer called Ron Lach. Being a person who read artworks, these cards were mesmerising. If I fall into compulsion, I might get these cards just for collection sake. Then again, my practical side will remind me that I do not stay in a big space, and I do not have a use for it except to have some artworks to look at.
