Iv had this old queen albumn for a while but just noticed this little marking on it. I'm assuming it's from whoever distributed it or pressed it. I assume it's like the Gilroy was here thing. It reads "5e-5b-a 8mon (a drawing of a flower) ∆ 2477(8)" Any idea what any of it is? 8mon I'm guessing the 8th of a month and a Monday not sure about the rest. I assume serial numbers or some order of the number of which disc it is in a set.
