'28 & '31 NY Yankee Team Photos

I have attached NY Yankee 1928 8x18" and 1931 13x20" team photos and the reverse of the '31 photo. I also have a Ruth family Christmas card that I suspect could be a copy from it's appearance but I dont know that, however I can not yet find where I stored it. If I remember correctly it says "It Would Be Ruthless Of Us To Forget Your Christmas". I bought the items around 40 years ago but am downsizing a little and hope to sell them. Unfortunately the larger 1931 photo is signed "to Ralph with respect and admiration, Jimmy Reese". Are these of any interest to anyone? I do not know what they are worth or how to go about selling. Thanks!
