 Medium-thin flat index stock poster is in BEAUTIFUL mint/near mint to near mint (A/A- to A-) condition; aside from a tiny bend in the upper right corner tip, it is an absolutely GORGEOUS example of this semi-uncommon mid-'69 Family Dog Great Highway poster featuring none other than the mighty Grateful Dead.
