How about NFT art the size of a stamp?
Mikastamp.com launched their website yesterday Monday. In the announcement email Mikastamp is described as:
"Mikastamp is a one person company with a big vision. I created this company because I wanted to create a brand that incarnates my hopes for the future of fashion, art and humanity. Mikastamp promotes a deep care for individuality and self-expression through authentic art sewed on well-made products. Bringing together creation and purpose, the brand relies on the technology of bitcoin for a world free of corruption through traceability and easy transactions. We bring art on the streets and we want our customers to let their imagination be their only limit. For this first release three different items are available from our in-house production. If you received this mail you can count yourself into our community. Thank you for your interest, let's create together!"
So the website sells physical NFT's that contain a QR code. Art can be bought with Money Button and RelayX wallets, or with Anypay or Stripe.
