Thank you for submitting your item for appraisal. This appears to be a decorative painting of the 1960s or 1970s, depicting a kitten watching two butterflies. The main colours are brown and yellow. Although the paiting bears the signature "Collins" lower left, it will most likely be just a pseudonym of a painting manufacturer or workshop like Vanguard Studios. Such paintings were produced for home decor and sold in department stores. The estimate is based on similar items offered or sold at auction. "Asking prices" in the trade can be higher and vary. A real cat enthusiast might be willing to pay more than the high estimate.
