Some of my family members keep a collection of refrigerator door magnets and always seem to enjoy getting a new addition. A big big favorite with friends is a "custom" bullfighting poster with the friend's name imprinted between those of two genuine bullfighters as part of the "program". I picked several of these up last November while walking through the El Rastro Sunday flea market. The vendor prints your friend's name on the poster while you wait. My boss is an avid bicycle rider, and so I brought her back a souvenir winter cap (although this was from Barcelona).
