<P> In 2015, Dairy Queen and model railroad company of Milwaukee, Wisconsin, Wm . K. Walthers came out with a Walthers Cornerstone HO 1: 87 Scale models of a restaurant--one from the 1950s with the original logo and one from 2007--present with the current logo . The models are both officially licensed replicas . </P> <P> The original Dairy Queen logo was simply a stylized text sign with a soft serve cone at one end . In the late 1950s, the widely recognized red ellipse design was adopted . The initial shape was asymmetrical, with one of the side points having a greater extension than the other, especially when matched with the Brazier sign--a similarly sized yellow ovoid, tucked diagonally below its companion . By the 1970s, both sides were more closely matched, becoming symmetrical with the 2006 update (see online images for comparison). Some of the new 1950s signs continued to display a soft serve cone jutting from the right side . </P> <P> "Little Miss Dairy Queen" began appearing in Pennsylvania signage in 1961 . She had a Dutch bonnet, resembling the ellipse logo, with a pinafore apron over her dress and wooden shoes . </P> <P> A yellow trapezoid Brazier sign, placed below the red Dairy Queen logo, was developed in the late 1960s . It matched the roofline of the new store design of the era . </P>
