I bought these too.
It is official. Mixtapes are almost impossible to find in the wild. Big thrift stores don't carry them, small thrift stores sometimes have them, but not often. People are more likely to throw away or keep a mixtape instead of donating them to their local thrift store. Even when you donate to the goodwill they throw them away.
So, I want to draw your mixtapes. I want your sad songs, you love jams, your sing at the top of your lungs car tunes, your break-up tape, your make-up tape and your BFF-4evah cassette.
I am only drawing the tape. If you want to participate, please snap a picture of the best side of your favorite tape and email it to me (see my profile) or upload it to your flickrstream and let me know.
