Here is our first publication by Dave Haselwood Books, an announcement for a collaboration by Bruce Conner and Michael McClure. Published in 1966, "1200 copies on 65 pound beige cover stock, saddle-stitched into 130 lb cover; text in 12pt Clarendon, versos printed with Ben Day dot screen (Johnston)." Give an assist to Haselwood as book designer, as this is an artists' book with text by McClure and mandalas by Conner.
Not to be confused with Lobe Key Stilled Lionman Laced Winged April Raphael Dance Wiry, which was also a collaboration by Conner and McClure, "11.1 X 14.2 Ultima laid envelope; Bruce Conner 1966 Michael McClure (on gummed flap); contains 24 cards 5 X 5 with 12 pt Joanna capitals; four words per card, bled mandalas on verso (the announcement for the next book) (Johnston)."
Seemingly similar publications but if you try to purchase them at a bookshop or online you will not confuse them due to a major difference: Mandalas is around $75; Lobe Key $1500.
