Johnny Cash and Rolling Stones concert posters

selling both together. both vintage posters are in good shape with some wear around corners. both are clear and visible and as olf as they are, it's amazing they still look so cool. I don't know the age but I do know t h ey were purchased prior to 1990. I'm not giving them away I rather just keep them. I realize duplicates can be purchased but these are vintage and show appropriate aging. they are extremely special and always are a conversation item with company
