I think ist's pretty kewl beans the stuff "memorabilia" that is out there. I've got this metal little STEELERS airplane believed to be 1936 vintage and it is absolutely kewl beans. The vender (at heinz field) didn't know what he had and I picked it up for $5.00. He wanted $25.00 (that's a steel) but I said way to much. He asked how much I thought it was worth and I said $5.00. He said no way...... I said when game was over I'd swing by and if was still there I get it for $5.00 he said ok..... I did and he did.
