Both of these are from the Levin Collection and come with Hake's COA. Although the name of the button manufacturer is not specified, Levin acquired these directly from that company. Each is 3". The b/w button was made for proofing purposes and his note on the back reads "Test 2/85." The actual finished button comes along and this has his note on the back "Coleco/NYC/2/85" with mark "5M" meaning 5,000 were produced. We're not sure exactly what product Coleco was selling but pictured is the character with the text "The Cat In The Hat By Dr. Seuss." Proof button is as made, essentially Mint. Finished button is essentially Mint. A unique pair.
