H Hargrove us air mail painting

I’m not sure but I think this is a serigraph as opposed to an original painting. If you google it you’ll find quite a few works by this artist including a few other airplane variations. The prices people are selling the for are all over the place. You can see identical paintings one selling for $60 and another for $300. Here’s eBay’s sold list for some https://www.ebay.com/sch/i.html?_from=R40&_nkw=H+Hargrove+us+airmail+painting&_sacat=0&rt=nc&LH_Sold=1&LH_Complete=1 where one like your’s went for best offer, something under $50. LiveAuctioneers has two airplane ones (not the same as yours). One sold for $25 and one for $75 https://www.liveauctioneers.com/item/43318203_h-hargrove-1941-italoamerican-original-oil With the estimate being $150 - $300. My guess is $30 - $75 is more likely.
