Circa 1981 Vintage NASL Chicago Sting Spalding Soccer Ball – Signed by 5 Players. Vintage and rare original Spalding souvenir ball from the NASL’s Chicago Sting from around the 1981 season. Signed on 5 panels by stars Karl-Heinz Granitza, Pato Margetic, John Tyma, Tasso Koutsoukos and another player. Shows very light use and wear and is a very presentable display piece. Yellow and black synthetic leather. Seems to be holding air still to some extent but I cannot guarantee the bladder will hold up to more air pressure.
