NFT Editions


Last update: June 20, 2022.

Mature Horizon is a generative digital art collection based on the artwork, “Mature”, an oil on canvas made by Ofill Echevarria in 2014.

© ‘Mature’ (2014) | Oil on canvas | 48” x 50” | 122 x 126 Cm.

The collection comprises a large number of emotionally distinctive Non-Fungible Tokens, with the exception that its first 3 numbers are identical to the original picture, but also unique as their color range varies.

Also, even though Mature Horizon features digitally created items, when you purchase a Mature Horizon NFT, you could actually own the digital asset you purchased in high resolution, which is no larger than 2100 square pixels, or 7 x 7 inches.
