I don't really have a problem with Dana's last version of the sticker, but maybe something like this would work with the vintage theme?
Not sure if it's old enough though.
Any maybe the wording should be "Daily Special" with "Valid one turn only - resets to 3 neutral" underneath?
Or maybe "Sale - today only".Could also do something like:
Valid one turn only - resets to 3 neutral.
Used this font: http://www.fontspace.com/disturbed-type/nashville
Or even put it on a chalkboard? But it seems there are too many chalkboards... if fact maybe the upper left chalkboard content could be written on the sign like the other comments on the bottom?
I suppose the amounts wouldn't be quite right, but it would look cool if the prices were in cents: 5¢ (it would probably have to be in the range of 50¢?)
