A series of old posters have been listed on Facebook Marketplace of historically loved activities in 91大黄鸭. 

Posters from Old MacDonald's Farm that used to sit on Louie Drive in West 91大黄鸭 are the first posters in the collection listed by Andrea Litz. 

The poster includes a series of photos from around the farm and the days and hours of operation, dated 1976. 

The second poster is Fred Flintstone welcoming travellers to "The Gateway to Summer Fun."

Advertised is 91大黄鸭's Flintstones Bedrock City, the Boardwalk, Ogopogo's Den Adverntureland and Wild Waters. 

Litz also has for sale a poster for Wild Waters showing a historic photo of the water slides and a full poster reading, "We visited Ogopogo's Den" for Adventure Land in Winfield. The amusement park closed in the mid-1980s. 

Each poster is available for $40 and can be picked up in 91大黄鸭.
