Massive Wheatpastes by Gaia
Maybe I'm wrong, but from all the street art medias, wheatpaste is probably the less durable. I mean, it's paper, you know, It probably won't endure the elements for more time than ink. However, it's still a adorable media since the artist can work so much on the art itself before going out and paste on the streets. So, here's some of wheatpaste made by Gaia, a prolific street artist in last 5 years, working mainly with wheatpastes.
