Card front (blank back)
Mr. Frey's teammate, (and #6) Johnny Vander Meer, went missing at some point, making this card perfectly suitable for this type collection. Most of the pictures look like Linus, vertical portraits with decent lighting. A few (mostly in the middle of the set) capture them at distance or in action, including a nice double batting shot of Ted Williams and Joe Cronin.
Though some show up as "individual" cards (probably thanks to kids from the 40s), most modern collectors go for intact Double Plays. They're not particularly hard to find, but anything pre-war and in decent shape commands high prices these days. I had the good fortune to score a complete set that'd been trimmed into pairs (and later reassembled using tape) for $300 last year on eBay.
Bob Feller always takes a good picture and his fellow Indian Joe Krakauskas looked happy to be paired with him, even if he couldn't crack the Cleveland rotation itself.
