Baltimore Bombers

The Baltimore Bombers were a proposed National Football League expansion team located in Baltimore, Maryland. When the NFL was awarding expansion teams to two cities in 1993, Baltimore was among the cities vying for a team. In their proposal, the potential owners of the team had settled on Baltimore Bombers as the team's nickname in honor of the B-26 Marauder, a World War II bomber designed by the Glenn L. Martin Company, and produced in Baltimore. “Boogie” Weinglass, founder of the retailer Merry-Go-Round, was one of the potential owners of the Baltimore expansion team.

Decision
Baltimore was not awarded an expansion team, passed up in favor of Charlotte, North Carolina and Jacksonville, Florida. However, Baltimore did end up with a team immediately following what would have been the Bombers' inaugural season in 1995 when the Cleveland Browns moved and were reborn as the Baltimore Ravens.

Proposed logo
The proposed main logo showed the silhouette of a "generic" WWII-era bomber (not the silhouette of the B-26 Marauder).

A link to the proposed logo can be found here and in the reference link (as seen on the notional helmet).
