I am asked a lot more often that I would have expected where I bought my trash/recycle can set, but I didn't buy them as a set, I just made one trash can a recycle can.
I just purchased two identical trashcans and a high quality, vinyl decal sticker in the shape of a recycle emblem. To attach I just used rubbing alcohol to clean the lid of the trash can where I wanted to place the decal, then simply peeled off the sticker backing and affixed the decal.
Here is a link to the exact sticker I purchased from Amazon: Vinyl Recycle Sticker
