Obviously Minor Threat is one of my favorite bands to collect.
Recently I found the Out Of Step tape with the $7 dollar post paid price on the spine. Collecting variants of tapes is probably harder than the vinyl version. First copy I have seen in years. Perhaps tapes is much more a throw away item compared to vinyl and the pressing run is probably much lower.
Another thing I got is this counterfeit the first demo tape. This one isn’t made in east-Asia as most bootleg tapes are, but this one is from the good old USA.
