Good photographs of Mini Capitán Boy and his equipment are very thin on the ground, so I can't show a complete set here, unfortunately. (Good photos will be more than welcome should you be able to take some!)
As a size indication, the Mini Capitán Boy figure is some 4 cm / 1 1/2 in tall. Photos below compare sizes between Mini Capitán Boy vehicles and their larger Capitán Boy equivalent.
note: there are some lovely photographs by a Mexican collector here, whom I've sadly been unable to contact to ask permission to include his pictures on this page. (opens in new window)
