The odds are 50/50 that the Abominable Snowman actually exists or did exist. (Humans have never captured an alive or dead Abominable Snowman/yeti.) However, one can extrapolate from alleged, physical qualities concerning the Abominable Snowman/yeti. These qualities/characteristics may help to determine if the Abominable Snowman/yeti can exhibit art in Chicago.
The Abominable Snow/yeti walks instead of crawling, flying or slithering. These cryptids are hairy and stinky. These creatures are shy. These bipedal beings have big feet. No one has proven that they are intelligent. Persons who claim to have seen yetis and Abominable Snowmen may be perpetrating hoaxes.
If an Abominable Snowman/yeti has artistic talents, it could likely paint and portray other Snowmen walking in Millennium Park in winter. Perhaps, it could photograph yetis ice skiing on Lake Michigan. Snowmen sculptures may be unmeltable snow and unmeltable ice encased in glass. Are you familiar with the artwork of O’Leary’s Snowman?
Being shy, Abominable Snowmen would likely be absent from their art gallery opening ceremonies. (Their shyness would require that they hire a human or several humans to hang their art in Chicago’s galleries, and represent them at galleries’ openings. Perhaps, these yetis would pay the humans with animal bones or souvenirs from Riverview Park.)
Any intrepid, Abominable Snowman who intended to appear in-person at a gallery open would likely appear naked. (Chicago’s police officers would likely arrest them before they entered the galleries.) Abominable Snowmen who managed to gain entrance into galleries would create a lot of excitement. (Some of the excitement would be art patrons quickly exiting the galleries because of the Snowmen’s body odor.)
It is unlikely that Abominable Snowmen can create art, or is it? However, appearances notwithstanding, Abominable Snowmen/yetis may be more intelligent and advanced than humans. Will humanity soon be able to view the movie, Planet of the Abominable Snowmen?
