There’s also the Lucky Luke story “The Tenderfoot,” when the titular British tenderfoot and his manservant are in a Wild West saloon and are given lager. There’s a delaying disturbance, at which point the tenderfoot observes that the now warm beer has become drinkable.
The last half of the Dillinger Gang’s bank robberies in 1933-1934 netted the robbers sums between about $17,000 and $75,000. Using that as a template, one might reasonably suggest that Scardol, in performing four robberies, might have collected anywhere between $60,000 and $250,000 in Depression-era money. Depending on how he got his loot, and when, there could be issues of the numismatic value of any stash (e.g., a pre-1933 batch of gold certificates, or high-denomination bills). The lack of notoriety and knowledge regarding his bank robbing might indicate, of course, that the take was smaller.
There’s the famous White Horse Cup Final, the 1923 FA Cup Final, where a simply gigantic crowd tried to cram into the then-new Wembley Stadium. The official attendance was an astounding 126,000 (the stadium’s rated capacity was 125,000), but there are estimates that as many as 300,000 (!) tried to cram in, and they spilled over clear to the touchlines.
(I wasn’t aware that the strip had retired the Percy character. Did he get a final strip?)
