Your vintage circa 1970's original paintings signed V. Carnelro were done by an unlisted artist. On today's market, these illustration art, paperback cover style paintings could sell for a high of $125 - $250 each. The suggested insurance or replacement value is $325 each.
Unlisted means an artist who has not sold publicly at an auction that shows transparent records to the public, thus establishing a known history of sales.
His works are not on listed databases with past auction sales. Please bear in mind that an asking price for a painting and an actual sale price can be vastly different. Any person can ask any price they want on any item they own, the key element being finding someone who will buy at the seller's pricepoint.
