Purposely made perforation "errors" exist and are being placed on the market as if they are something special which they are not.
Although this issue was authorized by the Guinea postal administration, virtually the whole issue was not sold in Guinea, but only distributed by the Guinea philatelic agency Stamperija for distribution onto the philatelic market. The massive numbers of issues produced obviously were not needed in Guinea and it is obvious they were made for profits from stamp collectors.
