For some reason they left out the poster in the hardcover.
I had also picked up the handouts book and it did not have the poster either.
Also, following is the errata that I noted while going through it and forwarded to Chaosium. (Some of it is picky, but some can stop a keeper in mid-game who is looking for information).
Notes made while reading through the hardcover edition of the Chaosium
Beyond the Mountains of Madness
A few of these probably qualify to be considered for an errata entry, some of them are aesthetic and have no bearing on the book, other than perhaps stopping you from smoothly reading a sentence to its conclusion.
One general observation and it might be the text editor used or by design, but the first paragraphs after a section or subsection heading is consistently not indented.
Page 12 -- middle column -- references 16x20 map which is not included in the book
Page 29 -- middle column -- last paragraph -- "fit-ting" should not be hyphenated
Page 33 -- middle column -- lines 11 and 12 are compressed together
Page 35 -- middle column -- "Aftershocks" last paragraph refers to clipping 3.1 and it should be 1.3
Page 39 -- middle column 2nd paragraph 16th line -- "how-ever" should not be hyphenated
Page 43 -- first column 3rd paragraph 10th line -- "detec-tive" should not be hyphenated
Page 61 -- 1st column "Pieces of the Puzzle" paragraph 7th line -- "Re-luc" should not be hyphenated & 9th line -- "Roer-ich" should not be hyphenated
Page 71 -- middle column -- bottom of paragraph references plan of aft rooms on page 268 and the plan actually is on page 270
Page 72 -- 1st paragraph refers to cabin 30 on the next page. The information is actually on the same page
Page 93 -- 3rd column -- 2nd paragraph "Stark-weather" should not be hyphenated
Page 122 -- 1st column -- "Danforth at Work" section -- last line missing the page number of the new spell, it is on page 177
Page 123 -- 1st column -- lines 3 and 4 are compressed
Page 126 -- 1st column -- 3rd paragraph 9th line -- "Lex-ing" should not be hyphenated
Page 136 -- 1st column -- where it refers to seeing "Hanger
H2 after clearing" it took me some time leafing through the pages to locate -- it would be of assistance to point the reader to page 150 for this entry
Page 141 -- 1st column -- "The Locator Stone" section 2nd paragraph 10th line --
"no-tice" should not be hyphenated
Page 141 -- 1st column -- "The Locator Stone" section last paragraph -- it would help to point the reader to page 273 when referring to chapter 16 since the information that this entry points to is buried in a paragraph without a specific heading
Page 173 -- middle column -- In the reference to the Second day -5ºF (-37ºC) there is a conversion problem. -37ºC = -34.6ºF. (I did not think to check any of the previous temperatures for accuracy, it was just that this one was obviously way off the mark)
Page 173 -- 3rd column -- "The Lexington Party, Dec 5" 1st paragraph 10th line "Antarc-tic" should not be hyphenated & 11th line "untrain-ed" should not be hyphenated
Page 177 -- middle column -- last paragraph refers to the new skill section before the prologue. It is actually on page 412.
Page 206 -- 3rd column -- "Elder Thing Parkas" section refers to "Entry Dome(page 208)" that information is actually on the same page (206)
Page 239 -- middle column -- 2nd paragraph -- reference is made to "roll on the Aircraft Failure Chart" -- this was difficult to locate and is actually in Appendix 2 on page 307
Page 255 -- "People Still in the City" section -- last entry has "Halperin256" with the 256 being meaningless in that context (reference to following page #?)
Page 261 -- 3rd column -- end of 3rd paragraph "Statistics for the Shoggoth are at the end of this chapter" the information that line refers to is actually on the opposite page #260
Note: I have not gone through the appendix sections critically
