Original, probably purchased in the late 1980s, vintage, transfer lettering, all Prestype brand.  All seemingly unused.  Some are sealed, outer plastic in varying conditions, but letters are pretty much excellent.  A great find.  They haven't made these in so long!  Possible very obscure fonts!! Sixteen packages/sheets in total.  ORIGINALLY PURCHASED FOR $4 EACH, but that was 30-35 years ago - they're worth about $10 each now - THAT'S A $160 VALUE!!! - Please see pictures above. Thank you and happy bidding!
