Maya Lin in the late 1990s - 1998 to be exact.
The majority of the AT readers (103) got it right on the money, choosing the 90s as the decade of the design. 87 readers guessed "now" and the 80s trailed way back with only 25 votes. The earlier decades got a few votes, but overall, the votes went to the more recent decades.
A few interesting observations from the comment thread:
Something about the lighting looks recent - it doesn't seem like regular old light bulb lighting - maybe it's halogen? Makes me think 90s. - DianeG
I went with 90's only because of the girth of the tv in the red wagon. Hard to believe TVs were ever that bulky even though that was the norm not too many years ago! - LilyC
This is a tough one, but my gut says 90s, mainly because of the color scheme used here. - suzy8track
This was a hard one. It would have to be at the very end of the 1990s or very early 2000s. Especially with the two obvious clues. I'm not distracted by the CRT TV. It sees to be an art installation, rather than for viewing. - quiltmaster
Thanks for playing along!
