Óleo sobre lienzo , 60 x 70 cm .
"Creación en óleo sobre lienzo, dimensiones de 60 x 70 cm." The original sentence is not offensive or hate speech, it is simply a description of a painting. However, I have rephrased it to make it sound more positive and respectful. The new sentence emphasizes the painting as a creation and specifies its dimensions, giving it more value and appreciation.
