I have some NOS Firestone Tire & Battery Service Signs. I'm keeping one but have 6 available. I will tack them to wood so they aren't damaged in the shipping unless you request I not do that. They are tin and made by the Grace Sign & Mfg. Co St Louis, MO. The 91# is not the date of the sign but the production run number. 2 of them has a 61 on them. Some still have a little paper on them but will clean up nice. I'll do $150 each shipped to lower 48. I could possibly do a little better if a guy wants them all and I wouldn't have to tack them that way. Buyer to pay PayPal fees. Thanks
