"Back in the Day" (Soul Bowl etc) there was lots of various records available in quantity that are now considered rare and hard to get.
The facts are, that in 2024 Eddie Parker with a large block print Archer stamp is hard to get! That's because any copies in existence are tucked away in hardcore record collections and not laying about in USA record shops or in the record bars of UK venues. If it was common, like people have mentioned, it would come up for sale once in a while. I haven't seen a proper one, on any of the major dealers lists or private sales for years!
