These are £15 on my Etsy & Ebay. Oil paint on A2 size paper. The paper is 170 gsm thick. Approx 60 x 42 cm / 23 x 16 inches. I did the writing in 6B pencil. I painted the painted text through a stencil I designed and cut by hand. The paper is cockled and curls at the edges.
About archival long-term effects: As the paper is unprimed, the oil paint will react with the paper over the years and cause yellowing and decay to the paper. I don’t know if the paper is acid free or not, but if it is, this will also cause yellowing over the years.
