Does anyone know anything about these:4" x 5" b&w glossy pic's of the 78-79 NY Yankee's. They all have what look to be ablue sharpie signature. I've had these for about a year and when I purchased themwas told no guarantee on the signatures. I sent the Munson into Jimmy Spence for authenticationand was told it was a stamped signature. I'm no professional but boy, under magnificationI even see light smudges from the pen on some and many are streaky like a sharpie will do at times.Any input would be appreciated.[IMG][/IMG][IMG][/IMG][IMG][/IMG]
