The department store nostalgia in today’s strip is pretty innocuous as Funky Winkerbean goes. I am enough of a retail enthusiast to know that department store nostalgia is totally a thing, by the way… but I’m not sure it manifests itself in wistful disappointment when receiving an Amazon package.
But since Amazon’s logo is clearly visible on present day Holly’s package, let’s talk about THIS:

There are several, actual historic and defunct department stores in the greater Cleveland-Akron area that TB could have pulled up: O’Neil’s, Polskys, May Co., the one that Dinkle named his daughter after, the particularly famous one that had the previously-referenced-in-this-very-comic-strip Silver Grill [sic] in it.
Nope, we get Holly’s memory of shopping at DS, which by all indications stands for… Department Store. DS. Department. Store. This is Herb & Jamaal-level non-specificity. Look TB, if you can reference Amazon specifically, you can reference an actual department store specifically. The strip loses nothing if you get Ayers to write “Higbee’s” on a couple of shopping bags instead of DS.
