These 3 showed up today. All are from 1974 (athough the Flatlanders text is copyrighted 1971, the artwork is copyrighted Children of God 1974 by the artist "Jacob Cartoon". The other two are illustrated by "EMAN Artist").
Flatlanders #57 (13 March 1971)
Heavenly Homes! #316 (21 October 1974)
Look of Love #304 (1 April 1974)
Unlike the previous 3, these 2 that arrived today are mini in size.
The red/yellow one "Lovelight" is illustrated by EMAN Artist and is dated 24 June 1974 and is #307.
The blue/white one "Richman, Poorman" is illustrated by Laban (Laban Cedar of Lebanon) and is dated 11 November 1974 and is #321.
So now we know that there was at least (probably more) 321 of these and we know of 3 artist from them (including Jacob Cartoon).
Sorry Arnie, these arrived today, if they had arrived Saturday then I could have included them in the trade items...
