Dunno if these were covered or not but I vaugely remember getting in the mail by some Matell promo a Race Team Deora, Charcoal Metallic Mustang with black stripes & a Metallic pearl Gold Twinmill... these were in baggies.

I tended to fill a couple holse of the redlines I missed back in the 60's, I picked up on clearance for .99 I think, a Vicki, & a Pink Deora included, plus a few others that caught my eye for the .99.
