I've done something similar with this ad and picture of my t206 cobb with cycle back as example (link below) and rec'd one response asking if it was available (duh), but another from someone I purchased "the $5 Washington elberfeld t206" and a run of vintage Baltimore cards, such as the one below. A very rare occurrence in my experience (mostly I don't receive any responses), but it is possible.
