New York skyline by windsor art company

I have had this painting since birth in New.York, my parents moved us to Florida and brought the painting with and has been on wall ever since. Its a New York City skyline by Windsor art, from Illinois moulding company. I believe its oil paint and in perfect condition, colors are vibrant. It has markings on back as seen in pictures, It's quite large. I have searched web and can find artist but not this painting. Was wondering worth value. Thanks
